[QUOTE="thomasbangs, post: 2340900, member: 49922"] I shoot a pre-64 Winchester Model 70 with a 26 in. barrel, I believe it has a 1 - 14 twist, the most accurate load I came up with was 38 gr. of IMR 4064 behind the old plain Speer 55 gr. SP, I use Winchester brass (after turning the necks) and Rem. 9 1/2 primers, that was the first load I could get 1 inch groups at 100 yds. with, a close second is the Hornady 55 gr. V-Max, also ahead of 38 grs. of IMR 4064 and same Win. brass and Rem. 9 1/2 primers, this will also shoot 1 inch groups at 100 yds. I am getting 3842 fps with this load. It seems that the 1-14 twist likes 55 gr. or lighter bullets with more bearing surface than the longer more bc bullets, the 1-12 twist should give more flexibility with bullet selection. I forgot to add I was talking about 5 shot groups. [/QUOTE]
