Looking for gunsmith info

[Bravo 51...Over]

Bob,

That's what happens when I work a 12 hour night shift and try to do things when my mind is not awake. The first bullets I tried are.264. Sierra and Hornady 140gr. I have some Hornady .268 160 gr. Carcano bullets on the way. I was shooting the .264 dia. when I learned the Arisaka barrels are .268. I checked the barrel with a micrometer and it does measure close to .268. The PPU 123 gr. do measure .267 (+/- .005). I wanted the 139 gr. but they were not in stock at the time.

That should be .0005. Dang mental cobwebs again.
