[QUOTE="Mikecr, post: 1731741, member: 1521"] Case shape is good reasoning, but with trending and polling of cartridge use in short to long BR competition, accuracy step changes follow: #1 shot rate #2 powder amount[B]*[/B] #3 powder heat potential[B]*[/B] #4 peak pressure #5 life extending actions (moly, melonite, etc) [B]*[/B] [w/resp to cal] A 26nos has a smaller bore than 30nos. Both 6.5x284 and 243win are overbore for cal. 308 and 260 and 243 use the same case, same shapes, barrel lives drop respectively due to bore diameters. Some cartridges survive longer with use of H1000, which is cool burning (magic stuff). Maybe I'm different, but I personally cannot stand shooting a gun with worse results than I'm used to from it. So I totally understand esshup's perspective. Hunting accuracy requirements are relative to a great many things. And given that accuracy is the most powerful of ballistic attributes, your true capabilities are heavily tied to it. When I’m positioned across a field to hit groundhogs at 500-600yds, presenting only their heads (due to grass height), I need 1/4moa. I couldn’t hunt that field without it, and them **** marmats know it. [/QUOTE]
