There's so much data on this topic I'm hesitant to even ask but here it goes anyway. I'm starting with a 381"-250gr cast bullet commonly referred to as the wet dog bullet. Long starline brass. I have gotten as far as figuring out that a .381 bullet is as large as I can cleanly chamber. And I've trimmed .030" off my brass to achieve a good length to crimp in the groove and not engrave the bullet on the rifling. Lubed with the infamous WWW....no red die or any coloring at all. I figure I will begin by trying the 10gr of unique. If anyone has any tips they have discovered on the cowboy guns like bullet jump etc. has anyone ran this bullet through a lubrisizer with any luck if so what lube may work well this way?
