[QUOTE="bblaine2k, post: 6785, member: 1440"] Hello gang, Well, finally got some shooting with my 7 mm RUM. You may remember me wondering how my Remington 700 Sendero Stainless Fluted may perform. Well, I'm still wondering, though much less than before. There's not much reload information for this caliber out on the market yet. In fact, I was only able to find out stuff from 3 powder manufacturers. Anyway, going with Hodgdon's recipe this is what I shot (albeit at 100 yards for initial load testing, longer ranges will be tested later) Cases: Remington 2.838", flash hole deburred and pockets uniformed Primer: Federal Gold Medal 215 Match LR Mag Powder: H 1000 Bullet: Sierra MK 168 grn. HPBT (recommended by this board over "hunting bullets" [img]images/icons/wink.gif[/img] ) Distance: 100 Yards COAL: 3.650" Firing was 5 shots per powder graduation, 2.5 minutes between shots, 5 minutes between powder graduations. 85.0 grains 4 shots within 0.375", 1 flyer (overall group = 0.65") 85.5 grains 5 shots within 0.71" 86.0 grains 5 shots within 1.5" 86.5 grains 5 shots within 1.5" 87.0 grains 5 shots within 2.0" 87.5 grains 5 shots within 1.25" I was so disgusted that I quit using my caliper [img]images/icons/mad.gif[/img] I talked with a good shooting buddy of mine who said that there shouldn't be that big of a jump in group size (since I let the barrel cool) I wholeheartedly agreed of course. My reloading technique is meticulous so I don't feel that is it. My only guess is that I need to clean the barrel between each shot or at least between each group. I've never had to do this before with other guns and still maintain around 1 inch groups. Can anyone give me any feedback on this? I did break the barrel in with 24 rounds of clean, fire, clean, fire techniques, maybe it needs more! Any advice at all? I know this rifle is accurate, the first group could kill a nickel at 100 yards! That, of course, doesn't mean didly at ranges of 300-700 (my goal distance). If it can't perform at a hundred then there's no chance it will perform at longer ranges! I'm eager to get a good 100 yard load and take it out to 700 yards. Again, any suggestions would be appreciated! Till then, good shooting! [/QUOTE]
