The first 1/3 (breech to 10”) will be over .100 it’s measuring approximately .113 now. The chambers are over .150. The muzzle will be over .065 which is .015 less than what it’s measuring now. I know twist steel is not comparable to modern CM or SS barrels. The minimum wall thickness for modern steels is .090 for the first 1/3 and .025 for the last 2/3. I won’t know the exact dimensions of my barrels until the pits are gone.
