Last year my Remington 710 30-06 was shooting 1-inch groups at 100yds. shooting 180-gr. power points. I upgraded the scope on it to one with coated lenses that let in more light this year. This year I haven't been able to get it to shoot consistently. I'm not sure whats wrong with it. I'm considering selling it at a pawn shop and getting a H&R Handi Rifle in 30-06 with a muzzleloading barrel to relace it. Any body have any idea what would make it so inconsistent from year to year orany input on the switch to an H&R?
