I pounded a .356 bullet through (no barrels were harmed) and it came out to .355
So it looks like the barrel is .355 at some point.
I have some 125 grn .38 bullets in .357 or .358 (I have to look at the box, it's been a while) that I considered using but tossed that idea after slugging the barrel. Plus with a Brinell hardness of 18 I didn't know if it would be too much pressure to go .003 over
Thanks for sharing your expertise. This may just be the first time I'm seeing leading PERIOD as all my other purchased 38's, 40 cal and 9mm Hardcast bullets left nothing in the bore except a bit of wax. Could be the cheaper lube.
