My Air Venturi Avenger-X shoots quarter size groups at 50 yds. with Predator GTO’s. I did crown and polish the barrel, but no other modifications. Squirrels don’t stand a chance with this rifle!

I use Predator GTO’s in my Gamo Swarm Whisper, I tried about a dozen Gamo pellets. They were a waste of money in my gun.

Did your groups get any better or worst, or no real difference? This sounds pretty drasti.

I’ll try that now!🐿️

I also tried some H&N FTT GREEN pellets and they grouped about quarter size. So I think my Benjamin likes lighter pellets that exit the barrel sooner.

thanks, I’ll find some leak detector.

By working on my air guns, I have been able to improve the accuracy on my “budget“ guns. Changing the triggers, changing scopes, polishing barrels, building scope mounts, and tightening ALL screws has made a world of differenc!

Necessity is the mother of invention. Glad you get to shoot!

I’m thinking of polishing my Gamo barrel with valve lapping compound, Flitz, and or JB bore bright. Should I use a brush or mop? Did your groups improve after polishing? Can I hurt my barrel?

My Trail NP XL does not group well with Premier HP 14.3 grains, but shoots dime size groups at 25 yards with GTO 11.75’s. Could the light pellets exiting the muzzle before the vibrations start? Any ideas why this difference?

Avenge-X will not hold pressure. I add air to my Air Venturi Avenge -X, and by the next morning when I want to shoot, the pressure has dropped from 4,000 psi to 2,000. What o-rings do I need to replace?

Great thoughts. I’ll start at 1,500 psi and work up. I’ve read that 15.89 gr. is good for 1:18 twist barrels, are JSB’s the best??

Thanks for all the input! I sprang for an Avenge-X. Next question, with 15.89 gr. pellets in a 1:18 twist barrel, what regulator pressure for best accuracy do you recommend?

In the $500ish range, + or ~ $200. Min
