Got some pretty impressive numbers from the gen 1 .22 Avenger build. 2800psi on reg, 3 turns on HS. JSB 33.95 @950s. 1 1/2" groups @ 100 yds. I will post target pics after sorting them for distance. Shot 500 rounds today. Lots of targets, lol. This .22 will easily hit 70fpe. Its a powerhouse. Very pleased with this build.
