Reason why I ask is that I had a .270 Rem. 700 (2002 model-synthetic stock) glass-bedded, barrel floated, and the trigger pull reduced from 7lbs down to 3lbs. Prior to this I had acceptable grouping (1.5" @ 100 yds). The gunsmith that did the work is well-known for his craft. In addition, I had him mount a new Leupold VXIII on the gun (with new Leupold STD one-piece base and rings). Since the work was done, the gun appears to have a mind of it's own, shooting left, right, high, low of my aiming point at 100yds. The groups went from 1.5" prior to the work to 4-5" at 100yds (same bullet). At first, I re-mounted the scope, base, and rings myself, making sure everything was tight. Again - at the range -- same result. I find myself chasing my POI with my scope. What doesn't make sense is that when I change my windage or elevation, say 2 clicks (1/4 moa)--- my shot goes off as far as 4 inches from the intended target. FWIW - I am used to shooting - alot. I de-foul my barrel every 15 shots, and I am holdling true to the target EVERY SHOT. Any ideas??
