Not directly on topic, but FYI only: I once stumbled and bent the barrel on my M70 7 mag. I thought it was ruined, but took it to a 'smith (Kings in Burbank CA) just for the heck of it. For $50 he straightened it.
The next trip to the range I first shot 5/8" @ 100 yds. The second group "opened up" to 3/4"! I told Kings I should bend all my barrels and send them to them!
