You won't go wrong with 308, I had a BLR in a 308 and got rid of it because occasionally when you would work the action and squeeze the trigger .....nothing would happen. It happened several times when shooting at paper and only once in a hunting situation. When I got rid of it I had found out other people had had the same problem. All with the 308. My buddy has one in 30 06 and it has worked well for years. Maybe it was a thing with the short action models??
I have a 308 in a winchester model 88 and find it to be a much better rifle (mind you it has a horrible trigger).
Just my 2 cents.
