[QUOTE="scottyd2506, post: 873786, member: 19778"] Thanks Brent It probably took me 20 years to shoot 1500-1600 rnds through my 25-06. I've tried many things, it shoots many 1/2 inch groups, but poi changes as I shoot, depending on bullet, the 90's shoot 1st to 10 shots in the same area, then slowly shift to maybe 1 inch lower at 200 yards , the 115's need a fouler shot, then the 2nd to 10 or so shots are fine. as it get dirty or fouled groups shifts more as it get dirty.. by 20 round it stop shifting but accuracy is crap, 1 moa at 100 yards, 7 inches at 400 yards etc and 12-14 inches at 600 yards.. clean it good and I'm 2.00 inches at 400 yards . I notice more and more flyers as it gets older.. I've been playing with it to shoot out at 600 or 1000 yards. and practicing and developing loads etc take many rounds.. I've put through maybe 400 rounds in the last few months It is my main coyote rig, and once I re-barrel it, I'm not going to burn it out pinking steel at 800-100 yards. anymore my personal limit for a shot on a coyote would be 600 yards. I'm not sure about the 10,000 round 300 WM, with enough cleaning I'm sure it shoots ok, 3 moa?? but throat erosion is from the inside chamber escaping in barrel, no cleaning can stop this. I've heard many people cleaim they shoot out their 6.5x284's in 800 rounds. Meaning, yes they will still shoot, but not with consistent accuracy (10 shots into 3/4 moa at 1000 yards etc) anymore. The 25-06 is even more overbore than the 6.5-284, as the 06 case holds slightly more powder, and .25 is smaller than .26. I plan to shoot 400-500 rounds a year, so 800 rounds is only 2 years for the great 6.5x284. I'm not sure how long most 300 Wm's barrels last, it is not that terribly overbore. the worst would be a 257 STW. I hear 284's last on average 2500 rounds or more, can get 2800-3000 fps from a 180. thanks [/QUOTE]
