LOL. Yep. I hope to reach a point where I will buy two brands of the same caliber but I’m not there yet.
Certainly for your edumacation, regular practice and shooting targets at long range, the .308 is a lot more fun.
Myself, I'd just as soon take my lever action .45 colt with homemade bullets and buckhorn sights to the 100 yd range as well.
Good shootin'
:)
