Lapping is essential, 400 grit sandpaper wrapped on a 1" dowell works pretty well also and will make sure your rings are actually fitted to the scope. Lapping and shimming a scope and bases can take several hours but if your scope is worth anything at all, you owe it to yourself to do it. Use good rings and bases as well if you can afford them. Talley rings and bases are very well made and I have never had an issue with them crimping the scope tube. Redfield are all right if you CAREFULLY fit them. Redfield rings WILL marr your scope if you don't lap them before installation and make sure you torque the screws properly using a good in-pound wrench.

good luck

The most effective way to stop scope travel is to lap the rings before putting the scope into them(rings). Using a one inch steel dowel about 12 to 14 inches long, drill and tap a hole(1/4-20 or 5/16- 18) in the center of the rod perpendicular to the length sort resembling a rifle bolt. Screw into the threaded hole a 3 or 4 inch bolt to serve as a handle. Assuming the bases and lower rings are secure, start with 180 grit lapping compound apply the "mud" to the ring halves and work the dowel into the mud and slide/ rotate back and forth until all the bluing or finish is polished off the inside of the rings. This process will allign the rings creating more surface to contact the scope and eliminate any deflective torque that uneven rings made. Repeat the process using 240 grit mud and at that time mount the upper ring halves snugly(not tight) and polish the rest of the job. When done note which ring halves mate with lowers and keep them that way. That is what all custom benchrest smiths and all caring shooters do to assure allignment and stop scope travel. Amen

it's close to a glue.it fill's in the threads and hardens to keep the screw for backing out, there are differant grades of loc-tite some you can remove the screw and some it's almost impossible,you want a medium,i,dont have any ideal where you are at,but most gun shops carry it also wal-mart has it,may be a differant brand though,auto parts shops carry it too, just look for a med strength thread locker,good luck and safe shooting,bobby

probely the scope rings are not tight enough,but check to make sure the rings are touching the scope all the way around,i have found some rings that wernt really round inside and not making good contact all the way,but more than likely they were not tight enough or the screws are backing out on you, you might try a little loc-tite,(not the permenet type),bobby
