Subgauge, thought CIP was 2.5 METERS from muzzle?

Not sure where I saw that.....and yup, could be wrong!

Also, does the British proof house have velocity testing standards at all....if they do, are they different than CIP? Would think they are mostly concerned with pressures?

Bill, it is wise of you to consider your crimp depths in the equation, it can make some difference.


Best,
