I am new to the BPCR game and I want to load my 45-70 rounds with blackpowder and I was given a good starting load of 60g of FFg behind a 500gn cast for my trapdoor.
The main question is: How do I fit 60 behind my bullet, and how much compression is enough or too much?
The reason I am asking this is the throat in my trapdoor is very short.
