[QUOTE="LRangepro, post: 317627, member: 9174"] I dont have a 7WSM but I do have a 300WSM and a 280 Ackley. For the sake of this topic, I'll talk only about the 280 AI. I've been shooting 168 Bergers with Reloader 17 with great results. I have gone just above 3100fps with the 168 VLDs and not much pressure and it shot really well. The load that shoots best is back at about 3050fps and it shoots better than any other powder I've used. Sub 2" groups at 500 yards and I've shot a few under an inch when its calm and cool. (no mirage) 100 yard groups are pretty much just a single hole but I dont burn too much powder at 100yds. No pressure to speak of. I think I've got 7 loads on a batch of Remington brass and they are still good. No marks on the brass at all, just a very slight flat on the primer tops, thats it. I think I can go higher but my brass is so free of pressure signs that I started to worry I had really hard brass or something. It sizes fine so I dont think thats the case. I dont think its magic powder but it works well. The burn rate is faster than the powder you'd normally use but the pressure curve doesnt spike so you can push it up there without issue. If you have a shorter barrel, its easy to see the benefits of a slightly faster powder. I have yet to do much testing with the 180s over my chronograph but they shoot too and I think I can get 3000 or at least close. The powder works well in my WSM but I havent used it as much yet. Vit. 560 is hard to beat in that case but RL17 might do it. [/QUOTE]
