[QUOTE="1984nitro, post: 1183489, member: 24113"] So I know there have been people out there working with 165 matrix in the 270 win hoping they can help. I worked with these bullets a few years back and wasn't seeing the velocity I want so I discontinued and when with 150 sst with good results. I have recently can back to the 165. I am running a 1/10" 26" barrel with 52.5 gn of RL-17 with mag primers. I'm getting an avg of 2919 fps over 10 shots. I am not concern with the grouping. The vertical was .63" and the hozontal was 1.2" with gusting 10/15 mph winds. I feel on a better day and better sd the group with shrink. My concern is the es of 62 and ad of 20. I feel this is in my case prep and reloading. I have turned all my necks, clean the primer pockets, weight each powder load. I have foster neck sizing dies. I load to mag length. I was wondering if I need to anneal the case,or play with the oal, or change the powder load +/- .2 grns? [/QUOTE]
