American Air Arms  Low powered Evol Mini tune

Anyone tune the Mini down to a lower power than the usual 28-30fpe they come at? I'm getting close to tearing into mine and tuning for the 12-14fpe range and was curious of anyone has a good reg setting for that. Doubtful anyone has but thought I'd ask. And if not I'll be letting people know lol. Mines at 2050psi at the moment and shooting at 30fpe. I'm thinking at least 1500psi would be where I should aim for. If not less.

N/A  The Venom Arms Company Story

Hi, folks! If you’re keen on a dash of history and fancy diving into the tale of the legendary Venom Arms—those wizards of tuning and customization—I’ve spun their story over on my blog. Plus, I’ve thrown in some cheeky articles about the Mach 1 and 2 rifles, along with the infamous Lazaglide tune. Come have a gander!

What Scopecams Are Available❓

What Scopecams Are Available❓


After Tactacam has sadly abandoned us (and I really invested into my Tactacams because I thought I really could trust them to continue this product!).... –
I am looking into another scopecam system!


Mind you, NOT one of those cameras that don't ever touch a scope, they simple are an action cam that mounts on a gun.
There are some joksters out there that sell these as "scopecams." They are just gun cams.

Mind you also, NOT one of those cellphone-to-scope adapters, we could call those maybe cellphone scopecams.

I mean, a real scope cam – cam as in camera. A camera that films through the scope – what I see in the scope is going to be on an mp4 file....
A system that doesn't take my beloved cellphone away from me every time I want to shoot.... Or requires a specialized mount every time I change my cellphone. 🤦🏼‍♂️



Anyhow, has anybody lately been shopping this segment of our hobby and can give me (and others) a run-down of what's available, and – I'm hoping – tell us the good & the bad of each system?

A few years ago I did a massive collection of info, instructional, and links about the Tactacam. Maybe someone else is up for the task to advise me this time.


Thank you! 😊

Ballistic apps and potential energy via gravity

I use Strelok and like it a lot, but since getting into ELR, I’ve been trying to get as precise as possible with my POI predictions. Strelok has a few mathematical issues that introduce small errors in the ELR predictions. There is one that I’m encountering lately. And it is present in other apps (ChairGun for instance) as well. Maybe there is some countering mechanism in the math that I’m not aware of, so that’s why it isn’t accounted for. If you like math/geometry/physics, you might be interested. After I explain it, let me know what you think.

This is a real example that I encounter at two different ranges.

Range (A) has a 600yd target down in a valley. -15 degree slope. That’s 466ft down.

Range (B) has a 600yd target up a hillside. +15 degree slope. That’s 466ft high.

Strelok (and ChairGun) show the same velocities and same required correction for both targets.

But a 105gr slug separated by 942ft of elevation has a difference of about 14 foot-pounds of potential energy. Certainly it took more energy to lift that projectile to the higher elevation. Where did that extra energy come from?

That should equate to a difference of about 30fps at the target. So why are they the same?

Instead of them both showing the same 104moa of needed correction, I would expect to see something like 106moa for the upward slope and 102moa for the downward slope. Am I wrong?

Gear bags, Go bags, how do you drag yor crap around?

I'm not a range shooter, I predator hunt. Big bore.
Beyond my c/f tank. I carry anmo, shooting sticks, range finder, assorted hand calls and a electric caller with remote. Other than the shooting sticks . I pack my gear in a medium sized chest pack. What do you use to drag your stuff around? And what stuff is your must have in the field ?

  • Question
FX  about tuning fx impact for pellets and slugs at the same time?

hi everyone

since the valve is a big factor regarding the tuning process of the fx impact
can i tune the gun for slugs and pellets at the same time?
for example the hammer wheel on 10 for jsb 34 gets me 920 and 14 gets me 960 on HN 36 gr slugs
OR do you think valve opening and closing will be an issue regarding accuracy while tuning for both ?

Offhand practice

In preparation for the AZ State match this weekend I forced myself to start a little abbreviated offhand practice regimen not quite two weeks ago.

Typical for most of us, I don't love offhand shots, and don't often practice them. So I went into this somewhat curious if semi-regular offhand practice would improve my shooting, or if ability/inability to shoot offhand is just inherent to muscle tone/skeletal structure/etc. I tend to believe that we get better at any thing we do repetitively (practice).

Used the pistol and the rifle that I'm planning on shooting this weekend.
PXL_20240915_003155414.jpg


Any pistol offhand is tough. But the porky little Veteran is an offhand challenge. Was joking with a buddy during this experiment/practice that the Vet in the chassis stock is like trying to shoot a cinder block offhand.

Each day I took 15 shots from each gun at a one inch orange sticker placed at 25yards.

No additional offhand practice on all but one of these days. Sometimes I was putting lights out and doing it at 10pm after work. Had a few days in there were I was sore from processing a couple pallets of firewood. That was interesting, to see the effect of sore muscles on trying to be stable from the offhand position.


Shared in the order they were shot.

So what'd I learn? First, there's just as much swinging around in the sight picture now as there was 11 days ago before doing this. However, it was very apparent during the shooting that concentration CAN be improved. And I mean con concentrating on timing the trigger pull with the reticle being in the correct place, "drive-bys" if you will.

It's also a delicate balance between being quick on the trigger when the crosshairs are in the right place, versus being TOO quick and pulling the shot. You'll notice some of the pistol groups have a rightward migration/tendency....yep, I'm right handed.

As for the pistol...I don't feel like I got anywhere with the offhand pistol shots, but certainly feel more confident with the rifle now.

And perhaps 10 days/sessions simply isn't enough to make huge leaps and bounds. Realistically, I used up what little dedication I had to practicing offhand in one fell swoop, and I don't plan on practicing even this earnestly anytime soon.

Since forced position shots, specifically offhand, seem to be every ft competitors bugaboo, thought it'd be interesting to share here.

Brocock/BRK  Pathfinder XR an under appreciated gem…

When I first received my Ghost Carbine, for a while I thought my Pathfinder was in jeopardy of being sold. Then I downsized the scope and fell in love again. The Pathfinder is but a smaller Commander or Sniper XR. With the TP on low, sending CPHPs, it has been stellar from 25 to 64 yards. Sure kills on small rodents out tp 50 yards. My groups at 25 yards with CPHPs when “I’m” on point? Simply… 💥💥💥 And while I really like my Ghost Carbine she is a portly gal, even in its carbine configuration… I have an Athlon Helos 6-24x50 atop which adds mucho weight. Am still in the process of sussing out da Ghost. The Pathfinder is an under appreciated, seriously capable PCP, first shot this morning? Dead on, second shot after an eight hour workday? Dead on… Am lucky that my trinity is composed of two Atomics, a Ghost and Pathfinder… So I get to contrast them at will. At the moment the Ghost is struggling to find it place in my repertoire… When the Pathfinder had the Aztec Emerald 6-24x50 it was simply too portly as opposed to the sweet WHT 3-12x44 it currently sports…

Organic Reactive Targets

I put in a lot of pickling cucumbers and yellow summer squash this summer and after putting up 18 quarts of fermented dills and giving them away I still had a lot. I don't eat summer squash because it has no flavor, but I know people that do like it. I had a lot of them that I could not get rid of. By now I think you know where this is going! A ripe Boston Pickling cucumber is about the same size as a squirrel body. Way more fun than paper or steel!

Alternatives to foot pounds of energy (fpe)

An often discussed topic is what sort of caliber do I need to hunt coyotes. Or squirrels, or rabbits. There are tables that show a person's opinion but many of us disagree with at least portions of the table. Another way of comparing is to calculate the fpe of a gun and compare that. Like I have had good experience with 22 and 177 caliber pellet guns at about 18 fpe but not so good experience with lower energy in both calibers. Perfectly reasonable way to communicate.

But airguns have to deal with the fact that our power source is really high pressure air but it is at hugely lower pressures than powder burners. A rimfire can be over 24,000 psi, for instance with center fires often over 50,000 psi. To compensate more powerful airguns go up in diameter. That makes sense because the larger diameter provides more surface area for the lower pressure to push against.

But then how do you compare larger diameter potentially heavier airgun rounds to smaller diameter potentially lighter PB rounds that are moving at much higher velocity. FPE can be used but many feel it puts too much emphasis on velocity. The velocity is squared in the formula. Elmer Kieth is an old gun writer that liked large diameter handguns and felt they had much more effectiveness in hunting than the fpe would predict. He is just an example, others believe heavier slower moving projectiles can work effectively and more effectively than the fpe would indicate. John Taylor was an old african hunter and poacher who came up with the Talor Knock Out Factor. I believe Chuck Hawks came up with the killing power formula. These are alternatives to fpe which place less emphasis on velocity.

Knowing this the spreadsheet I use to look at shot curves calculates fpe for each shot but also the Taylor Knock Out Factor (TKO) and the Rifle Cartridge Killing Power (KPS). I do not think either are necessarily better than using fpe but they are alternate ways of looking at the rounds effectiveness. I calculated the following comparison:

22LR target round with 40 grain bullet going 1040 fps. Energy 96, TKO 1.31, KPS .431
35 grain 25 caliber going 950 fps. Energy 70, TKO 1.2, KPS .275
45 grain 30 caliber going 900 fps. Energy 81, TKO 1.7, KPS .41
50 grain 30 caliber going 900 fps. Energy 90, TKO 1.93, KPS .5
81 grain 35 caliber going 700 fps. Energy 88, TKO 2.8, KPS .8

As you can see, a 25 caliber airgun would have to be very powerful to challenge any of these factors for even a target round for a 22lr. But a 30 caliber gets close on energy, is higher on TKO and a little lower on KPS. Perhaps the biggest illustration of the difference in these values is for the 35 caliber. This is a pretty low velocity 35 and it is still lower in energy than a 22lr but significantly higher on both TKO and KPS. There are on line videos of the use of the Benjamin Bulldog in 35 caliber on deer and African plains game. Power was probably pretty close to this 35 caliber example. But it worked. I don't think most would body shoot any of that game with a 22 lr unless they had to. Just another way of illustrating why the other factors may make some sense.

  • Question
Solved! Large FX Impact POI Shift Issues (Impact from Hell)

I've edited this to fix the several spelling and grammar mistakes. I feel really dumb after reading them all. 😂 Sorry to anyone that had to read the original post...



Hello! I'm new to the forum, but this seems like the best place to get advice. I am not new to airguns, but I am new to the FX Impact. I work on all of my guns—centerfire and air—and have never had this many issues. I'm almost ready to throw it in the trash.

I am including all of my problems, even though they might not be related.

Some Backstory:
I bought a Demo FX Impact M3 .22 600MM from Utah Airguns a few months ago and have had nothing but problems with it. It seems that every time I buy an airgun from them, there is some major problem with it. I guess I haven't learned my lesson. To start off with, my "functioning gun" came with a junk regulator (4 disks flattened and caused severe reg creep). Then I installed a new Huma regulator. It was also missing a few random parts that have been replaced. I installed a Slug Power Kit and had several issues with power consistency. I have since removed everything, but the hammer weight. I have installed a STX heavy barrel liner and a carbon fiber barrel sleeve. I have lightly glued the ends to keep the sleeve from moving. At some point the valve rod bent (not sure if it was like that when I received it or after, but it has since been straightened out within a few thou). The first stage of the trigger sometimes gets hung up and won't reset. It will then proceed to fire when on safe. I have tried adjusting it, but the issue always comes back. There have been a few other problems, but I'm sure you guys don't want to read an entire book.

I currently have about 450 slugs through this liner. I am currently shooting NSA 31.2gr @ 990fps. My tune is 1st reg @250 bar, 2nd reg @ ~173 bar, front valve adjuster @.404, macro @14, and micro @ 4.375.

Now to my current problem. Every time I take the gun out of its case (after sitting for a day), my zero/point of impact is severely off from the day before. It seems to trend down and to the right about 2" at 40yds (my zero). I have had some extremes as far as 4 inches to the right. I check my velocity every time I take it out, and it stays within 5fps of 990fps. I can refill my bottle and shoot as many rounds as I want, and it will not return to my original zero. When I put the gun away for the day, I lay it down on its side on a foam pad. There is nothing that should be tweaking the barrel. The temperature and humidity have stayed roughly the same throughout all of this. I have tried retuning my gun a few times, and it doesn't seem to improve my situation either.

So far I have done the following to try to help remedy the poi shift.

1.) Carbon Fiber Sleeve (I have never tried shooting this with the factory o-rings)

2.) Ensured that everything is torqued to spec (scope base, scope rings, backbone, pic rail, barrel clamp, set screw that attaches and holds down the barrel by the transfer port.)

3.) Put on a trusted scope that has never had any issues before.

4.) Retuned the gun and ensured that nothing was getting bumped.

5.) Checked weights and lengths of slugs to ensure I wasn't getting weird seating depth issues. Also includes making sure slugs are clearing the transfer port.

6.) Swapped to 25cal Donnyfl moderator in case it was clipping

7.) Used gauge pins to ensure slugs aren't clipping shroud.

8.) Holding the gun in many different ways (I have heard they can be hold sensitive)

9.) Removed all o-rings touching the outer sleeve of the barrel

Some potential issues that may be causing it

1.) The carbon fiber sleeve has about .010 of play inside of the outer sleeve. (Should it be a light press fit?)

2.) The scope rail does not allow for centered scope rings on the tube. The front ring has about .100 of clearance from the turret. It is currently sitting in the only place for proper eye relief.

3.) Possible bad o-ring that I can't find. (I have taken the gun apart several times and can't seem to find any that are bad.)

4.) The entire barrel system (related to the carbon fiber sleeve fitment)



I'm sorry for the rambling, but I am at my wits end with this rifle. Has anyone ever had this many issues with POI shift? How were you able to fix them? It would be nice to know why you decided to change the part(s) and how much it affected the outcome. I'm willing to try just about anything at this point. I don't mind spending money to fix it, but I am also getting really sick of dumping money into it. I haven't contacted Utah Airguns about this issue, but I will not be doing that. That's a story for another time. I have debated on putting an Airmarksman backbone on it, even though it doesn't seem to be hold sensitive. I have also considered sleeving the old liner and glueing the carbon fiber sleeve to the outer liner, installing a tensioner, or machining a solid barrel. This is a hunting rifle, so I don't want to add a bunch of weight to an already heavy gun as I walk several miles every time I go out. First shot accuracy is very important to me, and I can't trust this rifle, which is a shame as I hadn't heard of anything negative about these guns until I really started researching the issues I've had.



I've attached a picture of my scope mounting so you can see what I am talking about.



Thanks for the help!

N/A  PCP shotgun options?

I’m looking at pcp shotguns. I live in South Dakota so it would get regular use, especially with pheasant season right around the corner. Tons of birds are making their way into our pasture and tree line. I know I will be able to get a few with my rifle since they are often in my yard and on the edges. At the edge of my property there is a gravel road, directly on the other side is corn fields very high traffic area.
Shotgun would definitely increase my chances and would make it a lot more fast paced and fun.
So far I’ve found 3.
Seneca wingshot 2
Serpent arms 550
Umarex primal
Does any one have experience with these models and have any opinions?
