[QUOTE="Darkker, post: 2788591, member: 81406"] The 'concept' doesn't square with reality, is why. Every company uses a slightly different alloy, so the weight can vary, regardless of volume. Some cases are balloon head, and some aren't; again that affects weight more than volume. Pretending that any random case that's lighter holds more powder, is either nonsensical or ignorant of how production works. Here's the actual traces from the pressure testing, so you don't have to scroll up again; here's the case weights Lapua - 165.10gr Norma - 154.78gr Despite the case weights variation, the internal volume wasn't enough different to affect the burning curves in any meaningful way. Identical? No. Meaningfully different? Also no. Cheers [/QUOTE]
