Hello all, I have a question. What is the largest bottleneck case that you have loaded successfully with black powder and a cast boolit. I should add how did it shoot.
(Edited to add) The reason for asking this is I have a 338 barrel that I thought about building a BP and lead rifle out of. I have a lot of older brass that would be great with the lower pressure BP loads. The lapua case is large (117 gr H2o) and I was wandering if any one had any luck with large capacity bottleneck cases and black powder.
All input is appreciated.
