Are you asking for something that'll be more appropriate up close yet will shoot 150yds? 300yds?

.30-30 in those close 30yd ranges would be great, and now with that hornady ammo it has become a 300yd gone. 150yds it certainly will do. This would be my 1st choice at 30yds i think, esp since I already own it.

.308 might be nice for that situation, or better yet, 7mm-08! I think I solved your dilema. haha.

I certainly wouldn't be using the .300 mags at 30yds.

If you really are taking way more at 30yds, I don't think you could do better than a .30-30, it'll do 150yds no prob, and 300yds can be done.
