Designing the 2-diameter paper patch bullet.

[Distant Thunder]

Chris,

I sure do! They offer it in two sizes and they list it by the base diameter, which is the wrong way to list it IMO. Sku: JIM453545E is the .443" diameter version, that's the as cast diameter of the bore diameter section. It should patch with 9# (.002" thick) paper to .450". Then the JIM455545E is the .445" diameter version and I believe it should patch up nicely with Seth Cole 55W, but I would have to check my notes on that paper to be sure. Those using 55W should know what it adds. I have used it some but not enough to have the numbers committed to my aging memory!

Ideally the bore diameter section would patch to a snug fit in the bore of your rifle and the base diameter would patch to a snug fit in your fired and unsized cases. You could easily size the base after patching to suit, but sizing the bore diameter is much more complicated.

I would like to see how this bullet would shoot in my Shiloh .45-90. I think it would be a perfect bullet for that rifle and it's standard grease groove chamber. That project is on my list of things to due, some day!

Oh, the bad news is both sizes are out of stock and the demand will probably fairly high for a time. So you may have to wait to get one.
