My 700mt won't group anymore

stiffwindpsr · 11-23-2006, 08:00 PM

I've got a 700 in 270 that's close to twenty yrs old.The rifle's been glass bedded and has a timney trigger.It used to shoot close to moa but now I'm lucky to get 3"grps at 100.I've tried several diff ammos and they all spray.This gun has been shot a good bit and has seen it's share of hot handloads.Any ideas?Would it be worth the $250 or so to send it to someone for accurizing?Thanks

How many rounds has the rifle had put through it?

stiffwindpsr · 11-23-2006, 08:07 PM

I'dguess it's been shot 1500-2000 times.I keep it clean as well.

Have you checked the scopebases and rings?

Could have it rebarreled. If your loads were too hot and you let the barrel get extremely hot you could have some throat wear. you can save her!

Well I haven't checked the bases but the rings are as snug as they were 15yrs ago when I put them on with loc-tite.This rifle's rode beside me in the truck many miles and I suspect the crown may be damaged.Would this cause accuracy to suffer this much,and is there a way to tell if the crown is damaged with the naked eye?I don't have a gunsmith anywhere around here that I trust.

If the crown is damaged, your lucky it didn't affect it more, I have seen some really good guns ruined,just because of slight damage to the crown. They went from Sub-MOA to 5" groups.

How often do you use a single purpose copper solvenr, IE Sweets 7.62 or Barnes CR-10?

Yeah, copper solvents will ruin a barrel also, if left in there too long.
