So, I've been wondering about accuracy recently. I'm not the best shot in the world, and growing up my Dad and I would site our rifles in at 100 yards using a tent as a bench rest and not supporting the but with anything other than our shoulders. Basically we sighted in our rifles with the same technique that we used to shoot animals. We were happy with a 3-inch group at 100 yards when we sighted in our rifles, and I always attributed that wide group to our imperfect technique.
Well, my two hunting rifles that I now own are a 40 year old Remington .270 Model 700 and a 55 year old .308 Winchester Model 88. They have both served me well through the years, but recently I have been sighting them in with a proper bench rest and a rear leather bag and I still am ending up with a 2" to 3" group at 100 yards for both guns. I don't think that my technique is leading to this wide shot radius. Rather, I think it's my guns. Is this sort of accuracy issue something that I should have a quality gunsmith look at, might they be able to recondition a barrel to improve accuracy? Or, if I want better accuracy am I just going to need to purchase a new rifle. Should I be able to expect much better accuracy than that with a new Model 700?
I also wonder how my ammo affects accuracy. I mostly use Remington Core-Lokt with my .270, and when I've used some other brands of ammo I've gotten an even wider group. So, I do wonder if purchasing a premium ammunition would make a positive difference.
Any advice? I've kind of assumed that I'm in the market for a new, more accurate, rifle. But, I would be happy if I could improve my bench accuracy with what I have. Of course, my field accuracy is not as good as my bench accuracy, so if a 2.5" group on the bench turns into a 4" group in the field at 100 yards, I start to worry about shooting much further than 200 yards.
