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
