[QUOTE="Dr. Vette, post: 352778, member: 22335"] Dave, The first rifle I ever purchased was a Rem 7400 in .30-06, bought it in 1981. I still have it, and it will shoot 1 MOA. However, some of these 7400s are not nearly as accurate. You may want to first see how good of a group you can get at 100 yards before worrying too much about 500+ with that rifle. The only modification I made was swapping in different trigger springs to bring it down to a 3# trigger pull. It's still not a great trigger but it's at least improved to almost very good. Interesting article. He states that "in an ideal world (it obviously does not exist) you would be able to zero your rifle and scope combination at 100 yards at exactly the mechanical zero of the telescopic sight." Actually, using Burris Signature rings with their inserts + a ballistics program, I've been able to sight in my rifles for a 200 yard zero and match them within a few clicks of their optical (may differ from mechanical a bit) zero. And, this is done using a laser boresighter and the garage door 100 yards away acroos the street. :D Bring them to the range and find tune them at 200 yards. This could, of course, be adjusted if one wants to be able to add/subtract MOA for various yardages; I know some try to put the mechanical zero part way between 200 and 500 yard adjustments. I'm not sure how long ago the article was written but today you can get it a lot closer than he describes. Anyway, my point Dave is that you may want to test that gun a bit before trying to hot rod it into a long range gun.
