.30 Prohpet Tune

[customcutter]

I have a .30 caliber barrel coming for the Prophet 2 tomorrow. I have JSB 44.75gr Diabolos and 54gr NSA slugs. Does anyone have a tune or started reg setting they can suggest. Thanks

I got superb groups on my indoor range at 16 yards using FX/JSB 44.x gr Diabolos with the reg at 130 and the hammer near max. I forgot the turn count...sorry but it was maybe two turns from max. Sadly, it didn't like the NOE cast 55 grain HP slugs that shot well in an FX M3 Sniper and a Gauntlet 30. The two hits to the right were the 68 grain NOE Boat Tails, which it did not like either.

well.

Thanks, the reg is set at 130 now shooting .22cal 21gr H&N's at 1000 FPS.

Welcome. I have the velocity recorded somewhere......If I find it I will post it.

Id tune it to shoot the 44gr JSB's at 880fps. You probably wont have to do to much with it already shooting 21gr .22 at 1000fps. Your is running very high power and the .30 tune will be very close to what you have for the .22.

Thanks, maybe I'll get to try it out in the next few weeks.
