For those of you with the shorter R5M standard in 25 cal, what kind of velocities are you seeing with it?
Power tuning as far as what exactly? I’ve had an .25 R5M standard and .25 R5M Long and both were ok accuracy wise from about 880 to 920 with the 25.4 grain JSB Kings. Maybe I was just unlucky but I couldn’t get either to shoot the Heavies accurately any better than quarter size groups at 50 yards. I didn’t try slugs with either. I have an .25 R5 Super Magnum single shot that is much more accurate than either of the R5Ms but I never figured out why other than the barrel lottery?
if you love accuracy, set that speed at 890-895 and thats it!!! (with the jsb kings 25.4gr)
