Outstanding. Deleted the wrong one. WTG, lummox.
Ok, here's the problem:
A friend brought his dad's rifle to the range last weekend, hoping to fire a few rounds. It's a custom made (in Alaska, about 40 years ago) bolt action rifle chambered in '.338 Win' according to the stamp on the top of the barrel in front of the receiver. Beautiful wood and metal. Large aperture (55 mm) Nikon scope mounted on top. He said that his father had 'taken many large game animals with the rifle in Alaska and the western lower 48.'
He had with him a full box of ammunition; it was an old box, generally dark yellow with a red 'Winchester' logo. The box was labeled: '.338 Win Mag'; I don't recall the bullet specifics.
We were unable to chamber any of the rounds from the box, and we had no other .338 Win ammunition to try. The problem was that the bolt failed to close completely: the cartridges fit into the chamber with no apparent problems, and the bolt would move forward ok but stopped just short of being able to drop the handle. This happened with every round in the box, and as I said, we had no other .338 Win to try.
I shoot black powder almost exclusively, and I know very little about high power smokeless ammunition. Up until now I've understood there to be only one .338 Win cartridge, sometimes called '.338 Win Mag' and sometimes just '.338 Win'. Is that correct? Is there another cartridge we should try in this gun, or do we have a problem that needs to go to a gunsmith?
