Aoudns good so far. Just a suggestion, trackofthewolf.com has oxyoke fibre wads and walters vegetable wads. The OxYokes can be had lubed and other wise. I've found them to be good for lubing when BP loads are used as in ctg. guns.
: Masking tape can also be used to increase the diameter of undersize bullets. Works for us. RB's - less recoil, higher velocity. Depends on what the rifle wants.
: Shotshell primers are just fine for BP. It is the easiest of all powders to ignite.
; BTW - Swiss powder is roughly 20% stronger than GOEX. It actually approximates the better English powders, power wise.
