I have a Encore with a custom barrel 22" in 6.5X284. Loaded 50gr. R-22, 140 SMK's,Fed 210M goes about 2700fps. I then tried 50gr/H4350.140 Horn SST goes about2830. Very hot flat primer but barrel is opening fine. I know these are max loads but shouldn't it be faster? I would like not to be at max but still should be around 3000. Is the short barrel hurting me that much?
