[QUOTE="cornstalker, post: 509790, member: 12323"] A couple of things that may or may not help.... (I know nothing about the JLK. I am shooting 139 Lapua Scenars at .010" off the lands) I have a Savage LRH in 6.5x284. The stock barrel was a copper eating machine. I bought the Tubb's system and used the whole kit. It took .020" out of the throat, but otherwise worked perfect. Just thought I would bring that up in case copper fouling is stealing your accuracy. (Not trying to insult your intelligence if you have already put the super scrub on) Second, I noticed RE17 is fairly accurate and very fast in mine, but also had some wild ES numbers, (67 to 139 fps), and the barrel heated VERY quickly. Best 3 shot group was .603" and best 5 shot was .740". Worst was 1.978". The good three shot group averaged 2997 fps (50 grains). I tried some H4831SC and although the velocity dropped to 2844 (@ 51 grains), the ES was 12 fps and the best 3 shot group was .269, worst was .686 (5 shots). Might just try switching powders real quick if you haven't already and see what happens. Either way, I wouldn't guess seating depth would work good one day and blow it up the next. Could be wrong though. [/QUOTE]
