Original paper patched bullet designs?

[Distant Thunder]

I've tried a couple different designs and weights of PPB in my .50 - 1 3/4, but the one I've had the best results with is a 545 grain bullet. Because of the way my chamber is cut it works best if I use bullets patched to groove diameter, .510". I can still seat these out far enough to get 80 grains of 2F powder in the case, which is plenty for my needs.

I have a few grease groove bullets that all shoot well too, but I prefer to shoot paper patched.
