Ron, I once tried paper patching .429 hard cast semi-wadcutters and was unable to master the technique.

Nice shooting there old boy. Looks like that sinful sister has a new combo for knocking down those swamp donkeys.

Hard cast is not the way to go. The .429 was way too small. We need to get you set up. Ron

Those .429's are only .004 smaller than 11 mm. Is that enough to make a real difference? As I recall, you have two wraps of paper around your bullets. Wouldn't paper that's a little thicker make up the difference?

But then again, you must understand that I have no idea what I'm talking about.

Actually the difference is .017" my 11 mm bullets are .446

The thicker paper allows for more of a chance for the bullet to not be seated straight. 9# onion skin works very well. If the bullet is not straight at the launch then where it hits is anyones guess. Ron

Ah-ha. That do make a difference.

As the King of Paper Patching, you should post your tutorial in the reference section.

Ron,

Are you factoring in the paper? Being a machinist all my life, I had to convert mm to inch and inch to mm frequently.

To convert mm to inch, divide the mm by 25.4, but I'm sure you know this. Thought I'd post it in case any others would like to know.

11(mm) / 25.4 = 0.4330

To convert inch to mm, multiply the inch (as a decimal) by 25.4

1/4" (.250) x 25.4 = 6.35 or slightly over 6mm, which is .2362

BPS, I think what Ron is saying is that the 11 MM mold throws bullets that are actually .446. So the bullets are not truly 11 mm (similar to a ".45 caliber" mold throwing bullets that are actually .452).
