RAW Rapid Changed to an other caliber

[etiam.viviens]

I have multiple pcp (theoben and Raw) and I want to change one of my Raw hm1000x from .25 to .30. The .25 does a very nice 79.5 joule with JSB heavy MK2 with the regulator on 150 bar. Believe this is the standard setting of the Raw when it was new.

I have a .22 raw that shoots the .22 JSB .25,4 grains at 65 joule with the reg on 150 and it shoot the .25 heavy at 78 joule without changes.

Was wondering if I need to change the reg settings to a higher or lower setting when changing to a .30. And what kind of power levels kan I expect when I change nothing.

I wil be placing a 700mm AP polygon barrel no choke. And hope to shoot also some slugs if the power levels allows it

My Raw 25/30 setup by AZ. Both barrels shrouded . Reg @ 160 for both. Just swap and both shoot lights out.

Ok thanks,

in your .25 it does 52 ft-lbs that is about 70 joule
In your .30 it does 72 ft-lbs, about 98 joule.

My reg is at 150, so I will try it first without changing the regulator.

As my .25 does 79 joule joule I can assume that in .30 it does about 103 joule. A bit over 100 joule that is more than sufficient.

Most of the .30 Raw schooters use the 44 grain JSB is the 51 grain JSB to heavy or does it perform badly.
