[QUOTE="Trickymissfit, post: 931257, member: 25383"] I feel your pain! My last Remington 700 shot 4.25" groups with hand loads, and several well known BR shooters couldn't get close to that group size. I fought it till I got so mad that I completely rebuilt, but kept the OEM barrel (cut as much of the bad stuff out of it as I could). I would start looking at the once fired brass (unsized) closely to see what I had there. Is the brass strait? Look closely at the neck to centerline of the case. If you have the tools, pull the barrel for a better look at it. My barrel was so bad that it tore up tight patches, and I hope yours is better. Looking at the barrel, does the last three to four inches feel looser than the rest of the barrel? If so, be looking at a new barrel with the 7mm mag. What the barrel's I.D. looks like inside maybe a clue, but I've seen some rougher than a corn cob shoot some seriously small groups. It is critical that the muzzle end be tight! If it's loose you got a shot gun. The brass shavings are troubling. I give the action a serious cleaning, and shoot a few rounds thru it one round at a time without using the magazine. This will isolate the problem. You've already rebed the action, and even restocked it with no help. So I'd forget chasing that demon for awhile. But I'd still give the recoil lug and the bedded area a really close examination. You can have the action trued and setup as nice as can be done, but if the chamber and barrel bore are junk you still got junk. gary [/QUOTE]
