That would be the one way check valve, that's fairly common. If it's holding air don't worry about.

My standard Avenger makes a conspicuous squeak on each pump stroke when filling from a hand pump, so I suspect what you are hearing is normal.

Side note, the check valve on mine started leaking a few weeks ago, and when I repaired it I swapped the check valve ball to a stem type and discarded the spring. Your question made me realize I haven’t noticed the squeak recently. Not sure if that eliminated it or I simply became desensitized to it. I’ll have to check.

I have shot the 30gr with my vulcan 500 laser accurate 170 bar will get the 30gr going around 930 fps you will need a heavier spring you can use talontune spring

I have done a lot of tests on the Vulcan factory regulator and the Huma The factory regulator is amazing and very consistent build like a tank, but If you go above 170 bar It will become slower you may need to change the washer stacking it will fix this problem and make it recover faster Right now my v500 shooting JSB 18.13gr and the v700 shooting the 33gr precision slug amazing rifles and they will draw a smile on your face whenever you use them

Tryed to order a talontune spring online but keept saying somthing about my postcode mabe cos I'm from UK. Best I can get is a fx mk2 spring which done the job when I put my agt reg at just over 170 bar. Yes your right I had to turn it back down. It shot well for a few days an then went off the ball not sure y. That y I'm giving the huma reg a go. I got 2 agt regs so might have a play with 1 of the stacks. Any info on a stack. What I did notice with the agt reg in a tester. Anything 150 an under it would stop in the tester where it should. Then anything over 150 it would go past... release a bit of air an then it would go to what the reg was set at. Do that mean it's creeping. Omg av u see them hp regs lol monsters never seen them before until I came across 1 on here

if i had the money i would strongly consider this option, they must be coming out with a new model or line as these are significantly reduced in price. i generally prefer Mil / FFP platforms from my long range rifle days (but they also offer SFP versions) .

Amazon.com

it's not a two thousand dollar scope but it's in my opinion a pretty darn good value at $415 dollars. I just can't afford it right now.

the only major negative at least for me would be the parallax value but it sure would work well for me at the distances I tended to shoot at.

On that amazon page, the 4-16x50 is better for hunting than the 6-24, no? I already have a Athlon 6-24 but the pov is not suitable for hunting. That 4-16 looks good at $374

My grandpa "pa" used to raise award winning Redbones when I was a kid. He had many dogs featured in coon hunters magazine. Tricycle Annie and a lot of her pups turned out to be amazing hunting dogs. Sus Vide, cock pot, and basting while slow smoking all have turned out great for me. Haven't tried many other ways but they are hard to beat in my opinion.

Awesome find!

Raccoon is delicious. Lots of trimming. The fat is a little gamey but the meat is like a rich roast beef. A 25lb hanging raccoon is only about 8lb of meat but I'll spend an hour rather than trashing then if they look like a healthy one.

I have been unable to find the reference material that I mentioned earlier on the piston ring dimensions. It was on the old Yellow forum, and has been relegated to history now apparently...

I did come across this write up though, and he measures 2 new rings and the old one in the rifle. I am gonna guess and say that you are good to go at .034 to .036.

Resurrection.

Is this correct?

OK, I admit my head is hard. I thought I was starting somewhere in the middle and working both ways, but until someone challenged me, it occurred to me that I wasn't working in the upper direction far enough. I thank you for setting me straight and making me think.

As to the question of reg plenum refill, yes, I have tried all different "timings" and nothing definite has appeared. Some "quick" shots are high and some low, and the same for longer waits. So, I've adopted the 15 sec rule for the most part, even though I take one shorter here and there simply because that would be how I shoot and I want to know that scenerio also.

So, Here's my new plan based on you guys getting my head in the game.
1st reg 150 bar, 2nd reg 100 bar, FX 18.1 gr pellet. Just somewhere to start anew.
My plan is as follows
(screw turns out-power wheel setting)
0-7 shoot 10 shots
1-7 shoot 10 shots
2-7 shoot 10 shots
etc until I find the point of no increase in velocity, they go down the pw 7,6,5 etc and backward til the plateau is found.

I'm only partiall done, but can make some definite conclusions.
0-7 861 fps avg, 27 fps es, 8.0 stdev 9 shots
1-7 922 fps avg, 27 fps es, 7.5 stdev 10 shots
2-7 961 fps avg, 29 fps es, 9.2 stdev 10 shots
3-7 980 fps avg 11 fps es 4.5 stdev 17( I threw out one shot that was extremely low, and assume it was a bad pellet)
4-7 990 fps avg, 12 fps es, 3.1 stdev 15 shots
5-7 992 fps avg, 10 fps es, 2.7 stdev 14 shots

Conclusions: (updated)
The plateau is around 992 fps. This pellet in this gun is probably not a great choice, but lowing the reg might do the trick. It likes to shoot above 38 fpe, at least with this pellet.

Next up is lowering the reg pressure and repeating the full test.

Thanks for that information. I've never seen a discussion on pellet shape or length. I have a lot to learn.

Funny nobody mentioned how the cow with her legs so close together could stay standing

Have you tried to contact Huma concerning your issues with their product? I have found the customer service from Huma to be wonderful. It is interesting that their web page for the regulator states "Fitting instructions are currently not available". Hum, you are on the cutting edge.

There are similar aftermarket "big" bolt handles for PB rifles like my Ruger Precision Rifle. This one is called the "Hammerhead."

View attachment 577127

I'm surprised someone isn't making them for the Marauder.

Click to expand...

The mrod, at least my gen 1...is a pain to do. Lots of heat for all the loctite and a lathe were involved just to prep the original bolt handle (I turned the original ball down and threaded it 1/4-28)and the stainless monstrosity is bigger than any powder burner one ive seen in 25 years of shooting. I went obnoxious on purpose because I was so pissed at double feeding and blowing up essentially all of the delrin components after the muzzle.

Its very silly proportionally. 2" long by 3/4 Dia. It is hollow tho. The disco got a longer rod and a leftover charging handle from the aea parts I used to make. I standardized all my goofy handles to 1/4 28 so I can swap them around to test.

that's awesome, thanks for sharing.

wish i had your talent. I used to just mark areas with a semi-permanent marker in red and always ended up redoing it after each match.

i would perhaps suggest something a little quicker and easier to read.....for my eyes, less busy is quicker and easier to acquire especially if time is critical. that was true for me in local competitions.

a bold color to differentiate from the standard turret markings would d also help.

(i copied this photo from the internet).

dialing had become so comfortable for me over the years....its kind of like the buttons on the old SLR cameras that i used to carry all the time...i got so used to where they were located it was so easy and quick to manipulate

Apologies for bringing up an oldie, but a great ttuning thread imo.

I have a thought for conversation...,My .22 zelos likes 870 fps for the 18.13 pellets. I have gotten there bumping up the reg, and backing off he h.s., and vice versa with the same group sizes. What are your thoughts.

My set up with...
1. Higher reg psi, and less hammer spring feels ,and sounds sluggish compared to...

2. Lower reg. and up the hammer spring? Seems snappiier, and quiet.

let's leave shot count, sd and es at the proverbial door for now. I am more interested in finding if your rig groups better with a higher reg.?, or more H.S. Tension to get to the same fps?

Thanks for your ideas....

I always set up my guns more along the line of #2. Just like the second post in this thread states. Set just a tad below the max velocity the gun will produce with a given reg pressure.

I was wondering what this means about moderator? What special mod you need with 580cc and 600mm barrel??

Click to expand...

I think already mentioned but a 580cc bottle on a 600 mm impact does not stick out longer than the threaded end of the shroud. You can use any moderator you want.
