I went to the range again last night with my new Rem 700 ADL .30-06. So far I have been amazed at its accuracy, as in the couple of times I have shot it, it has given consintant 1"-1.5" groups of five at 100 yds outdoors with cheap factory ammo. In fact it has also shot a couple of 0.5" groups of three, although it is probably my inexperience that is the limiting factor. However last night I had a problem, I started by shooting a group of 5 in a nice 1.25" group although about 1 inch down and to the right of the bull, so I adjusted the scope a couple of clicks and then changed the target. Next session i fired a lot more rounds (maybe 15-16 in a few minutes) and again tweaked the scope a couple of settings. the last shots were bang on the bull. Great I thought. I then waited a few minutes for the end of the session changed the target again and prepared to fire my last five rounds, expecting a nice group right in the bull. Unfortunately I got a nice group but this time about an 1.5" high and to the right!? I figured it must be my Simmons Aetec scope not holding zero but the range master said it was more likely because my barrel had heated up alot on the previous session and then cooled down again before these final shots, causing it to go off target slightly. Sorry for the long winded story, but can anyone confirm if this is a known issue with the 700 ADL, and if so is there anything that can be done or should I just live with it. I guess in the field overheating wont be a problem, but it makes it hard to get the scope zeroed precisely.
Thanks for any advice.<img src=icon_smile_sad.gif border=0 align=middle>
