Right at 147 FPE. Very nice. Dang I thought I had the market cornered for those heavy slugs lol. The 75's shoot very similar to the 80's for me. Just about all of his slugs from 60 grain to 85 grain are very accurate.

Yeah, probably better order some more before the word gets out and I can’t get my hands on them. Gonna be 2 dollars a round by the weekend.

I probably bought a couple thousand rounds from him lol. His stuff shoots good out of my .25 avenger with TJ barrel as well.

Seems like it wants to max out at about 155 ft/lbs. My last increase of 5-10 bar didn’t add any speed, and I still have plenty of hammer left. Don’t think I will try and go any faster. Just about every group at with the 75 AVS running ant 965 are .25 inches at 42 yards. About the same with the 70 grain slugs at 985. Worsts group today out of 13 5 shot groups was .39 inches CTC.

My thoughts are if it doesn't go faster with more pressure then the valve simply isn't being forced open enough or the valve itself is limiting the gun. We know the valve is much bigger than my maverick so that can't be the issue. That leaves me looking at the hammer relationship. Perhaps even with more hammer spring the lighter hammer just won't deliver enough energy to give you more power. May require a heavier hammer... I myself use a 26 gram hammer along with a stronger hammer spring to open it up at 200+ bar. The only other thing I can think of is barrel length not being long enough to take advantage of the air being used but still it should keep increasing velocity no matter what the barrel length is given an increase in pressure.

Getting about 11 shots at the power level. More than I’ll ever need for my type of hunting.

I’m drooling over these ballistics. More energy at 300 then I’m getting at the muzzle with my maverick tunned for 44.8 pellets

These figures are impressive, i just picked up a Panthera 700 in .22 but haven't had an opportunity to get some seat time in yet and this has me jonesin.

I have the tungsten hammer but don’t know what it weighs. So what you are saying could be a factor. Got some 80 AVS in the mail today and will test them at 100 in the am along with the other weights. I did chrome a few at 950 this morning. So 160fpe, I’m pretty happy with that. That’s the biggest slug that will fit in the mag anyway.
