I do think there is a role for both bigger compressors that are not easily portable and the little portable ones. For local travel I just take my bottle. But if I want to shoot a lot the bottle will get empty and because it's expired getting it filled is not simple. But a little portable...

In order, my PCP purchases have been Prod, Avenger, P35-25, P35-22 & 177, and Caiman X. I've owned the Prod the longest and it has needed zero repairs. I still enjoy shooting it. I shoot the Avenger the least mainly because it is so long. It leaked initially and was fixed under warranty but...

I am also right handed but left eye dominant. One of my uncles figured that out when I started quail hunting with him so I've been shooting from my left shoulder for around 50 years now. Trying to shoulder a gun on my right shoulder feels very wrong. I have a couple PBs with the bolt on the...

Target Forge has parts for at least some of the GX compressors.

I doubt fatigue is a cause of failure in high pressure air storage tanks because the number of cycles is so low. I do not expect to fill mine 1,000 times, I will not live long enough. Others may do much more but fatigue is typically at much higher numbers of cycles (often millions of cycles...

I make furniture as a hobby. 4 bedroom sets in my house, 3 in each of my kids houses. A dining room table with 10 chairs for my house, a kitchen set for each of my kids. I've also made stocks for 4 of my PCPs. Only the little stock pieces for my Marauder pistol are special and the wood is...

I think the best source of well documented data on SCBA tanks is the Navy report. They have never had even a leak from anything other than damage to threads caused by hydro testing. No "explosions". They use thousands of tanks. Solid metal tanks might "explode". There was a video on this...

I don't own any of the under 500W compressors but I agree with the sentiment that they are meant for filling guns. The CS4 may be an exception but due it's size my understanding is that a bottle fill takes hours. I use my Yong Heng compressor, approaching 3 years old at the moment and going...

I am a retired mechanical engineer and many years ago I had classes on materials and creep behavior. I agree that aluminum always creeps, it just creeps more at higher stress. Steel kept below it's yield stress does not creep. But that does not make me want a steel air tank. I would take...

I used to think that the FX externally applied rifling with the associated and seemingly necessary thin barrel was an interesting and possibly very good idea. Then others said the liners are not smooth inside as I assumed but are at least as rough as conventional barrels. Then I heard of POI...

How about the SPA P35X. It's heavy for my tastes at 2400 grams which must be about 7 lbs. But it has a 530mm barrel, a wooden stock, and a 60cc plenum. Plenum volume is a shortcoming of my P35s in 25 particularly and this should solve that nicely. Huma Air has them at under 500 pounds which...

I look at BC as something best measured instead of calculated. I use values published by hard air magazine or, if they are not available, data from the ammo provider. What I really want to know is the bc for that projectile from my gun but they can't provide that. If you want it bad enough to...

I shoot in my backyard into a pellet trap filled with rubber mulch most of the time. I have a "know your limits" target too and one metal squirrel target that get some pellets too. Behind my yard is a large lake with the homes on the other side over 200 yards away. I am shooting down so the...

Looks like the 3-12 is the best deal. I prefer the 6-24 SFP which was not shown on that link. I got the one I have from Krale. But if you are in the market for a 3-12 this could be a good deal.

It looks to me like the shot impacted about an inch lower than it needed to for the coyote to drop immediately. I think it probably died but it might have taken days. My experience is almost exclusively squirrels. I've killed the grand total of 1 small raccoon and no coyotes. I've taken 58...

I sometimes play with wind speed in Chairgun to get an idea if it is credible that the wind affected my results. You can input both the wind speed and the direction (and the bc, velocity, etc.) and it will give you the drift. I'm sure other trajectory programs do this. My best 100 yard groups...

The only thing I do is compare chronographs. I don't often compare them but I have. My inexpensive Chinese chronographs used to be a few fps different from each other but I shot one of them and I think the replacement compares better but I would have to do a more controlled comparison to be...

My P35s, made by SPA, will have a lower velocity on the first shot if I turn the hammer spring down 5% from the setting that gives peak velocity. At short range it doesn't affect POI much but at longer range it would. After the first shot the velocity is back where it belongs and steady. With...

I've never owned a Hatsan or a big bore. Hatsans seem too heavy to me. I own three SPA guns, P35s. SPA makes the Notos even though they do not sell it under their name. I have had to replace O-rings in two of my three P35s. I've had them 2-3 years. Based upon how the replacement O-rings...

Arken EPL-4 is my most expensive scope and I really like it except for the combination of FFP and a really fine reticle. It is a 6-24 and the reticle is not visible at 6X and barely visible at 8X. I like 6-24 for airguns because you can hunt at 6X easily and 24X is good for short range target...
