What are you loading?

What are you loading?

Winchester 38-55, I know there are some differences in barrel size depending when made.

are you talking about cast lead oversized to bore?
Ten thousandths of oversized lead?

Are you loading cast lead bullets? Or jacketed bullets?

If you have an older rifle, have you slugged the bore?

It sounds like a really small issue and one that I probably wouldn’t even notice if we are being honest, but a lot depends on the bullet, load, and rifle involved.

I have had some real goat ropes loading cast lead bullets in older rifles. We have one Spanish El Tigre, a licensed copy of the Winchester Model 92 in .44-40, that we must have put 500 rounds through trying to find something that shot well. If I never have to resize another cast lead bullet, I will be very happy.

I've had problems with the oversized bullets from Bayou and ACME before finally settling on Blue Bullets, which are not oversized. Now in all fairness, accuracy was great with both of them, and the problems seemed to be firearm specific. Long and short, XDm's have tight chambers and don't seem to play nice with the oversized bullets in my experience. The problems occurred with my XDm's in 9 and 40, as well as my dad's XDm's in 9 and 40 and RO 9mm, so they seem to be fairly repeatable (at least with Springfield Armory firearms). The ACME's actually seemed a bit more oversized than advertised, per my calipers. Think I was generally getting .3565 instead of .356, while they Bayous were .356 consistently.
