Well lil gun is out on my rifle set up the chrono and loaded up some 20g vmax 5 of each at 9.2,9.3,9.4
First two at 9.2 went 3646 and 3657 i was suprised to be almost at book max velocity on that load then shot 3 went 3580 and sure enough blown primer. Chronoed my factory ammo at 3570. The other day i went to 9.5g before it showed pressure signs when i didnt have my chrono now im having blow outs at 9.2g way to unpredictable for me I think I will grab some cfe blk and try to shoot for 3550-3600 fps if that doesnt work out this gun is getting fed factory 20g heck it might anyway shoots darn good with factory
