[QUOTE="sable tireur, post: 1499760, member: 27307"] This is the list of factory twist rates vs rifle models: [B][I]244 Remington - 1 in 10"[/I][/B][I]....Rem 700[/I] [B][I]244 Remington - 1 in 12"[/I][/B][I]....Rem 722, 760, 740, 725, 40-XB; Sako[/I] [B][I]6mm Remington - 1 in 9"[/I][/B][I].... .Rem 600, 700, 742, 760, 660; Browning B-78; Ruger[/I] [B][I]6mm Remington - 1 in 9"[/I][/B][I]... .Rem 700, 4, 6, 7, 7400,7600[/I] [B][I]6mm Remington - 1 in 10"[/I][/B][I]....Rem 40-XB; Schultz and Larsen; Ruger #1, 77; Browning [/I] Is it possible that the patch or the brush slipped while you were checking the twist rate? If your 1:10" is correct, I suggest cleaning the barrel thoroughly then examine the crown to see if there might be some damage. Other than that, there are methods to check the bedding which might have a problem or one of a dozen other problems. But in the end, remember that 1" groups used to be the normal and your rifle might just be that normal. Regards. [/QUOTE]
