I sort of belong to the "one of each" type of philosophy.
Shotgun: Remington 870 Express 12GA.
Rifle1: Marlin 30AS .30-30 with plain iron sights.
Rifle2: Savage 110 .308 with a Bushnell 3-9x40 scope.
I bought the Savage .308 because I just can't see myself putting a scope on the ol' .30-30 as it just doesn't look right. Plus I just can't get rid of it or sell it now that I have the .308 because it is a timeless classic and is fun to shoot.
I know Hornady makes the LeverEvolution rounds for the .30-30 but I haven't tried them. My Marlin, for some reason, prefers Winchester Silvertip 170gr. I have the rear iron sight set at 50 yards and use it when I'm in the thick brush and real heavy woods.
The Savage .308 is dialed in dead on at 100 yards. I still need to get it out to 150 yards or maybe 200. But, I remember when I had it locked into a buddy's bench rest, and it printed a 3 round cloverleaf square in the bullseye using Federal ammo.

Well then again, I had the scope maxed at 9 power and was at 100 yards. I do know this... Ol' 99er was right about Savage rifles shooting Federal ammo. My Savage won't shoot anything but!

The Remington 870 12GA doesn't have a preference. It'll shoot anything, no matter what I feed it.
