Aaaa Okay only made it to 300RUM.So we've covered everything from 6 dasher to 300rum. Hope that narrows it down for the OP!
Lots of suggestions, and we still don't know hardly anything about the intended use.
Well how about the 30-378Weatherbee.
This is still being used in LR Competition
And I have one and Love it.
I guess you can load 150gr in it for Whitetail, 180gr for Mule Deer, and my favorite the 230Hybrid for Elk, Grizz, Moose. Take a look at a 30-378 for hunting and long range shooting.
