hey BASEBALLCRAZY i feel your pain... i have the same gun but in left hand and it wouldnt shoot the winchester ammo worth hell.. i would suggest switching to a different brand of ammo... I switched to remington Accutips in 130gr and i get 5 shots in the size of a quarter at 100 yrds.. and i have had nothing done to my gun (trigger job). these bullets arent much more expensive the the winchester. like 22-24 $ per box.. you should give em a try..
I shoot:
Remington BDL LH .270
Bushnell 3200 FireFly 3x9x50
Browning A-Bolt .270 LH
Bushnell 3200 FireFly 3x9x50
shooting 130gr Remington Accutips
