No, don't do it. If the manufacturer rated the can for .308 Winchester, they won't warrant it against failure if you fire a 300 Win. Mag. round through it.

Originally they were rated up to 300WM, but I guess that changed.

Looking for the best whisky glasses? There are a lot of opinions when it comes to the best whiskey glasses. Many preach that the tulip-shaped copita glass is ideal for presenting the spirits’ aromas and flavors.

So wait, you're basically using a 308 load (same primer, powder charge and bullet) in your 300WM? If that's the case, then you should have slightly less muzzle pressure (larger case volume) than you would firing that from a 308. I'm working through the same issue on my .204 right now, Griffin is giving me some data that I can't wrap my head around and I think I'm ok to use my 22 can on my 204. Haven't gotten any replies here, just spam lately it seems, so I'm going to roll the dice.
Proper grammar is awesome.
