Good choice and you chose "just enough" of an edge over a PRB. I would go one step further with using a White 451 or MK in 45cal just because it is slightly easier to insure the barrel is clean and they are both fairly simple designs. Plus the big 451 slugs fly a bit flatter than the 50cals. I would probably choose Swiss powder too because it has some of the best performance and milder fouling.

The main point i was making is that there is nothing new about subs, they have been around since roughly 1890. Fast twist has probably been around just as long. Magnum caps might be considered "new fangled" if we exclude Musket caps. 209 primers are far from new fangled as well and work fine. In a FPJ they might even give an edge over the elements and are easier to handle for some people.

Buckskinners and traditionalists are quick to point out the limits they want to impose on ML hunting seasons but in reality most of them are just as guilty as someone shooting a Savage or most modern inlines in terms of ballistics. When you need or want meat on the table tunes change just enough to give you "the edge".
