Got one for you:

.22 HP 23 inch barrel, reg 152ish (damn baby gauges…), blue spring:

AEA 25.3gr at 950fps on PW 16
AEA 21.9gr at 915fps on PW7
Hades 15.89gr at 940fps on MIN (they’re surprisingly accurate at that speed).

Could obviously shoot 18gr as well but the gun/barrel likes the 3 mentioned above so no need to try a 4th :)

thanks @greenbeans - i'll add it now.

Still waiting for the BRK slug barrels, or Sub-MOA to come out with a 22 barrel. While the 30 barrel is a heavy hitter it is a bit to large for what I would like to do. I want to use my Corbin Press and make custom slugs for the rifle. So now I am stuck waiting, but with the 30 cal shooting around 980 fps the pellets are grouping quite nicely at 100 yards. I found that the accuracy issues I was having was due to pellet clipping in my Donny! Swapped units and she is quiet and still as accurate.

I am curious if the HP model would be able to rock a little smaller barrel, and use a unit on the end. Not sure if there is enough space there for an end barrel unit or not. Would make for a compact and fun truck gun.
