We go shooting 3-4 times a month. I only use my -06 for elk and speedy goat hunting, so all I do is make sure the scope is good before the season. Been putting more 55 and 63 grain downrange lately. Just got my AR10 lower, so been thinking about pulling bullets and powder and putting them in 308 brass. Oh, can't forget the 9mm either, got my wife one of those Hi-Point carbines and after shooting it, got myself one too. She's in the rings with almost every shot at 100 yds and I put one on paper at 200. For the $$ highly recommend those little carbines. My 16 yr old daughter with the 380 Bersa at 15 yds, you can cover her group with a soup can lid. My son's not great with a rifle, but used to consistently hit 23 and 24 out of 25 at the clays.
Garand isn't necessarily an attitude, but a power level. Garand loads are lower to avoid bending the operating rod. Loaded ammo for Garands will indicate that on the box. The local Cabela's have .30-06 on a regular basis, I don't buy it, because I only have a Garand in .06, and they usually have the standard loads.
