Doing the .300 winni I would opt for a bolt. Hunting big game and having a follow up shot can be a big advantage. I know what everyone will say you have to close enough and make the shot count but we aren't shooting praire dogs. A lot is on the line when you put the smack on a bull elk. I want everything going for me. 06 is another great caliber with many uses and all the gun MFG make them and factory loads are everywhere.
