So I talked to the fella that designed my 260 reamer. I'm trying to figure the actual length to the lands. So he give me this calculation of the Ogive at .262 diameter and the an OAL of 2.178 to Ogive should touch the lands at .262 diameter on the bullet. He specifically said .264-.002 to Ogive. This doesn't make sense as my Stoney Point 260rem gauge is 0.256 in diameter. Also I have a Bartlein barrel and the specs for that are 0.256 bore diameter. Does anyone have any idea what this fella is talking about with the whole .264-.002 Ogive calculation?
I have a copy of the reamer diagram. So what is the best way to calculate or measure OAL to Ogive.
thanks,
