I have a 270 Win that is in synthetic furniture. I want to tweak it. Just finished sending it off for a trigger job. The gunsmith will only reduce the pull to 3.5 lbs, that should be sufficient? My question is can a synthetic stock be easily glass bedded? How much would this improve my accuracy? The gun is shooting about 1 3/4 inch groups now? I know my technique is ok, as the 220 swift is shooting .5 MOA groups
