Thin paper v thick paper?

[MIEagle]

I’ve always wondered about ordering a mould based upon the thickness of your paper. It seems like very few of us have the ability to measure to the nearest .001, I know I don’t. Even bullets as cast vary somewhat, and of course alloys that may or may not be what you think they are. Paper is cheaper than moulds, and paper is not always consistent. There is no magic match, so spend more time at the range learning what works better with what you already have. That’s my process, but you won’t find my name in the winner’s circle. I just try to improve each year, and I think shooting skills are more important than load development.

My rifle is a C. Sharps 1875 in .40-60 Maynard. C.S told me their bores are .403 and grooves are .408. The chamber cast measured .40835 on the lands but we didn't have the anvils to measure the grooves. I'll go with .403. Measuring paper is very difficult so what I did was measure a .443 slick that I use in my .45-70 with both papers, measuring the new diameters and back out the .443. So, as stated earlier, I'm wondering whether a thinner paper is better that a thicker paper. I haven't had problems with the rolled paper curling up on me. Thanks for the replies.
