[QUOTE="Bart B, post: 1149678, member: 5302"] One really good thing is the SAUM cartridge doesn't have that belt. Belted cases are a problem for getting best accuracy. Another's the sharper shoulder angle which lets primers detonate more uniformly; shoulder setback from firing pin impact is less. And that leads to longer case life. And its short, fat case lets powder burn more consistently. All the really accurate cartridges are short and fat for their caliber. [/QUOTE]
