NO. Never use any ammo in a firearm that is not listed as safe to chamber and shoot in it.

Are you one of those kids that would always say "WATCH THIS!" when you were growing up?????

I bet you still are.

Your rifle will be stamped as to the cartridge to be used.

Don't do it. It is a one shot deal that could involve dismemberment.

Actually, this is one of the few times you can get away with using a different cartridge than the rifle is chambered for. This is because they share the same parent case and can headspace on the belt, and because the Win case neck is just long enough to make it into the Weatherby chamber's neck.

On firing, you will basically fireform the Win cases into .300 Weatherby cases with about a 1/32" neck. They will be useless for reloading, but nothing will blow up either. Accuracy will likely be reduced due to too much freebore as well.

You can also safely fire .300 H&H rounds in a Weatherby chamber, which will fireform them into .300 Weatherby cases.

In short, you are better off with the Weatherby rounds, but in an emergency you could use the Winchesters.

John Mazza, I concur. I actually held a 1" group using a vanguard .300 wthby mag firing .300 win mag. The only injury I experienced was I was cleaning up brass and took my muffs off and decided to fire a cold bore shot after the rifle cooled down and forgot to put my muffs back on. I was under a canopy and my ears are still ringing after 6 hours. Lol. But yes. It is safe. The weatherby chambered rifle is made for much stronger pressures and surprisingly did well. It fire formed the casing but had no problems extracting and the casing was intact. As for the rest of you, you have proven the fact that you shouldn't believe everything you read online. I did my research and experimented with a cheaper round.
