Home Forums Hunting & Shooting Hunting Rifles Single shot rifle- best all around cartridge- tell me!

I am going to purchase a single shot rifle, Ruger 1, Dakota model 10 or similar and I am looking for opinions, as we all know, everyone has one.

What would be an ideal all around cartridge for whitetail, mule deer, black bear, maybe an Elk if the opportunity comes, but not necessarily. Also what about barrel length? I am going to have a custom barrel made.

Yes, I hand load also. GO…...
