    RTI Prophet P1 .22 Efficiency & Power question?

    Just to clarify, I have superior heavy liner barrel from FX 1:16 twist which I think pretty standard for some slug action. They group great, and I'm happy my P1 now, lowered velocity to around 925fps 27gr .22 slug. And the gun holds zero day in day out. And I understand that P1 was not designed...

    RTI Prophet P1 .22 Efficiency & Power question?

    It's a huben cricket regulator, pretty reliable one. My RTI failed and couldn't find parts locally so I machined an adapter to fit that reg into my gun. I have no issue with pellets but with slugs, I feel that the gun is working hard to produce 55ftlbs (27 grain .22 shooting around...

    RTI Prophet P1 .22 Efficiency & Power question?

    P2 is a beast no doubt. It has the balance valve and very light hammer. By my P1 just has traditional valve so I dont think it can match M3 in terms of power. But I love my P1, holds zero much better than my M3.

    RTI Prophet P1 .22 Efficiency & Power question?

    I'm filling to 220bar, shooting 27gr slug @930fps out of fx superior heavy barrel, 1:16 twist. How heavy should the hammer be in your P1? Thanks mate!

    RTI Prophet P1 .22 Efficiency & Power question?

    Thanks for the advice. But I really feel like this gun is not producing near as much as it should compared to my DIY gun with 24gram hammer, lighter cocking, shorter barel, same projectile & pressure. I think a 31gram hammer, stiff cocking force, longer barrel like Prophet 1 should produce...

    RTI Prophet P1 .22 Efficiency & Power question?

    Hi guys, Coming from M3 owner, I've bought a used prophet P1 and was pretty impressed with the low profile design. But the max power and efficiency is poor compared to my M3 (of course) and even my DIY gun. So normally I noticed that M3 has 20-23mm hammer travel and relatively light hammer...

    RTI Good combination for hammer weight, travel for .22 600mm & 27gr slug at 55-60Ft lbs

    I'm building my own .22 (5.5mm) PCP with 20-24inch (500-600mm) barrel and trying to come up with most efficient setup. So by valve's gonna be traditional valve, not balanced of any sort. shooting 27gr slug, at around 950-970fps out of 600mm barrel (might be lower for 500mm), and running around...

    RTI Prophet II standard valve 'upgrade'.

    How's new valve hold up mate? And what's your efficiency like? with 27gr shooting how fast and the shot count from 220bar down?

    RTI RTI Prophet vs Impact M3 for mild slug hunting gun

    That was very helpful guys, I think I'm leaning towards P2 & Vulcan 3 (heard good reviews about them recently). For me, my previous M3 was never a "reliable" gun in my dictionary.

    RTI RTI Prophet vs Impact M3 for mild slug hunting gun

    Thanks. That's what I felt with my impact. Wondering POI. Not major issue for bench rest but a pain for hunter. I'll look into buying a P1 or P2.

    RTI RTI Prophet vs Impact M3 for mild slug hunting gun

    I owed an Impact M3 and was pretty impressed with its capability to shoot slug accurately. But when it comes to holding zero day in day out, my M3 does do a good job and it's a bumper trying to rezero my gun any shooting session. Just few clicks like 5 to 7 ckicks but I don't like the idea of...
