How long are they? We could compare them to a 69 gr matchking. That would be a safe way to proceed with matchking data, if the lengths are comparable. I have to work tonight, but maybe colt 51 would break out the calipers to help you out...I just measured a few and got an average of .895"...of course the profiles will be different, but it's a start that might help you.
I concur on the charge weights above.
I load the 69 gr to 2.246" oal and 25 grains varget. it is a compressed load. I am about to experiment with 24 grains to see if i can get 10 more rounds out of a pound of powder. If it's accurate i will stick with that.
