Re: Big Seven Case Capacities
This is quite interesting.
I wonder how, for equivalent barrel lengths, with powders currently available, a 176 grain 7mm bullet could be pushed 150 fps faster than a 178 grain 30 cal from the same Lapua case?
I mean, conventional ballistic wisdom says powders have to get slower, or charge weights have to get smaller for equal pressure performance. Or barrels have to get longer (maybe significantly so) for the same weight bullet in a thinner tube to go as fast, let alone significantly faster. Interesting...
