I have several rifles but just go to the range and plank around. For the 100 yd I don't really need a scope but over the last week I have noticed my eyes changing. Still 100yd and a decent iron sight, and I'm alright, but I know next to nothing about scopes, for instance should I buy a nice one and is their quick mounts that I can interchange from rifle to rifle with minimum adjustments? Or is it one scope one rifle. I wouldn't even know a nice scope from the pos I have on an ole lever action 30-30. I'm kind of looking for something that has some distance to it. I have been looking to buy a 308 and start to get into some distance shooting. But I would like to see my targets from the bench when I am working up a new load. Cause lets face it walking down range after every ten shots suck.
