N/A 55-60fpe compact .22

[TitanRebel]

55-60fpe is a lofty goal for a .22 - I'm not sure physics makes it possible for sub-34 inch .22 caliber to get that FPE... "comfortably". Is it possible, sure, but it's gonna be working hard. Maybe prioritize either caliber (and be happy with 35-50fpe) or FPE (and be willing to step up to .25 or .30 caliber).

RTI Prophet might be similar to what you're after, they'll get a .22/25.4 over 1000fps pretty easily.

2nd this.

I have a P1 .22 20” CZ barreled Compact that with a mild 127bar reg setting and 22gr JTS pushed at 895fps for 39FPE Just bumping reg pressure 5bar would easily jump the FPE into the low to mid 40s with the same pellet.

So, yeah the P1. 50+ FPE with 25.4gr..easy peazy.

OAL is 30.875” with moderator

True, and I misread the title thinking the request was for a 25Cal lol.

I will be customizing a Zelos .22 to shoot NSA 27.5GR slugs this weekend.

I will be shortening the barrel to 500mm giving the overall length 30 inches.

These are very promising guns.
