[QUOTE="scottyd2506, post: 873694, member: 19778"] As the title says, I would like some advice on a long range 1000 yard cartridge that does not burn out the barrel. I have 3 bolt guns.a win 70 300 win mag I bought in 1986 that has a THIN bbl, and shoot 150's at 1 moa and the 168-185 burger at 7-8 moa (not .7 or ,8) or 8 inches at 100. I've been toying around at 600-800 yards going for 1000. Hit a 8 inch steel plate at 800 with my M77 25-06 and 115 going 3200 fps. Problem is it's not consistent like it was, it's a 20 year old gun and has a good 1500 rounds through it. it used to consistently shoot 1/2 moa or better. but I get flyers more often than not now a days. My Sav 204 is fairly new and plenty accurate. shoots 1/2 moa all the time, and lots of 1/4 moa and less if I do my part.. but the wind past 500 kills those little 39 grain bullets. so it's out So I'm left with My Armilite Ar-10 shoots mostly 1.5 moa except the 175 SMK's that print 1/2 and 3/4 moa. It has a hvy 24 in bbl and 308's barrels do last forever. It is fun to shoot, but hard on brass and not as pin point as the new bolt guns Thinking of a re-barrel or another action. a long range bolt gun that can reach out, buck the wind and is not hard on the throat of the bbl. close to ..67-.70 bc and 2800 fps and last past 2000-2500 rnds and be accurate the 6.5-284 is good, but hear it burns out after 800-1000 rounds. (No wonder my 25-06 barrel is going south) the 7 mags also I hear are hard on barrels. The 260 Rem I hear plenty good things about. launching low .6 bc bullets at 2800 fps. the 6.5x55 Sweede another. I'm looking at the high .6 bc bullets, 6.5 Matrix 160 (.680-700 bc), .277 Matrix 175 at .680 Bc, .284 Berger 180 Hybrid at .674 BC. and 30 cal Berger OTM 215 (695 bc and 230 at .743 bc I'm not sure the 260 rem can launch the 160's past 2500-2600 fps, the Sweede might fair better. The strait 284 shooting the 180s at 2800 fps, the 270 wsm I'm not sure how hard it is on barrels, the 270 would be nice but magazine length with the VLD's might be a prob. a 277x284 might be a good choice. Then we have the 30 cals. a 300 win mag could get the 215's at 2900 fps and 230's at 2700 fps from 27-28 in tubes I have come down to these 284 win (can have in long action and seat bullets out far. shoot .674 bc 180's at 2800 fps) 260 rem .680 bc 160 at 2550-2650 fps prob last 3500 rounds even the .618 bc 140 VLD at 2800 fps is hands down much better than a 308 shooting .496 bc 175's at 2600 fps I'm shooting with now. 6.5x55 Sweed (or improved), 160's at 2600-2700 fps 270 wsm with 175 Matrix at 2900 fps (not sure how long throat will last) 300 win mag 215 at 2900 or 230 at 2700 fps and .696 and .743 bc (with a brake) any ideas to calibers you all would chose? thanks [/QUOTE]
