what make and model do you have?
I compete with a MAC1 airguns USFT (#27, .177 cal). Tim McMurry (builder) has put out a little over 400 last count and the last set he did had a bunch of heavier calibers for extreme Benchrest and extreme Field Target.
My operating pressure range is 1300-1600 psi, and I get 50-60 shots at a tight 900-910 feet per second velocity. The rifle doesn’t use a regulator which is the fail zone for a lot of PCP rifles. Mine’s had over 100,000 rounds through it at least, and (knock on aircraft alloys) I have yet to put seals in it 🤣
I’ve also got a UMAREX (.177 bolt, magazine fed) , LoGun (.22 cocker, magazine fed) and an old Mexican break barrel springer.
Review of one with some decent pics.
