[QUOTE="wareagledg96, post: 842050, member: 22055"] The twist rate is the question that eluded me initially. I can't find published data on the 260 steyr pro hunter. The rifle I bought was "new" old stock that someone never bought and I figure it is left over from around 2005 that is the last time I am aware they were sold but it was still in the box packed in original grease. When I check the twist the old fashion way with a rod and patch I a getting 8.6 as the twist. I have checked on a half, a full and two rotations and get the same number. It threw me when I first checked it because I rushed through it thinking it was something I have done a hundred times so on the first run it was slightly over 8 so i thought 8 and the patch was not tight enough. So to verify i ran a slightly tighter patch and it was just short of 9 on the second pass. Then it caught my attention so I slowed down and made sure everything was correct and ended up with the 8.6 which I can repeat anytime I check it now. I have never heard of 8.6 as a twist rate but that is what it is. So I am hoping the 140s will be stabilized by the 8.6 and I need a different powder COL combination. Again any advise or past experience shared is appreciated. DG [/QUOTE]
