Here is the deal. I have a .50 cal bore that I measured putting a brass rod and a 320 gr REAL bullet down the bore. When I measured it came out a whopping .509" That's loose.
I want to try the REALs but the rifling just barely cuts the top ring of the bullet. I've read on here that teflon tape works well as a bullet patch. I have 2 different widths 1/2" and 1".
Should I make an "X" over the bore and start the bullet on top using the 1/2" or wrap the bullet with the 1"?
Or,should I get some linen paper and use that? If I do that, do I grease the paper prior to wrapping?
Instructions/guidance please. This old fart is in need of some learnin.
