Same size bullet, 270 vs 284, that's close, never said it blew the action up, blew the bottom metal and wood apart

Showing him an expended case did not convince him and he said he had been using that ammo for years and to mind my own business. I would occasionally find one of his fire formed cases when walking in the woods. Cleaning up our range one day I saw a odd, expended round on the ground. It was quite obvious what had happened. Someone was shooting a 300 Win Mag in a rifle chambered for 300 Weatherby.


Seen that, make a very short neck, was at the range on day and the guy two benches down was shooting a wby mk5, I notice his fired brass out of the gun, asked him what caliber he was shooting he stated a 300wby, told him that's no 300wby case turned out to be 300win ammo

I don't know how I looked up the .270 bullet diameter wrong but I did. Jamming a 7-08 that has a .315 diameter case neck where a .270 with a .308 case neck is expected must be a hard shove or a sloppy chamber.

Was thinking the same thing.

Full disclosure. I once fired either a 6mm or a 260 (can't recall) through my 270. Pulled the trigger and thought- wow, that was like zero recoil. No harm to me or rilfe but a serious wake up call.

When I first started shooting I ordered some ammo from a reloader. He asked how I liked it and I asked him why I had to beat the bolt to open it. The panic he expressed convinced me not to repeat that. Live and learn....if you are lucky I guess.

I was shooting with a guy who fired a 7mm-08 round through a 30-06. Sounded funny and no hole in the target. Looked at the case, straight walled it. No adverse effect, except for pride.

He only keeps the ammo he’s shooting on the table now.

The 708 neck would never be no where near the 270 neck

Had a buddy from work want to get into hunting. Very humble guy, admitted what he did and didn't know and wasn't afraid to say it. He's a good dude, so after listening to some dumbfûcks offer him bad advice I said if you want help I'd be glad to if you want it.

Took him to the range to sight in his rifle, and I look down and there are a couple boxes of Barnes Vortex 7-08 rounds. I asked him to look at his rifle again and read the roll marking on the barrel. He had a 7mm rem mag. Nice gun, wood stocked tikka, decent scope and spendy ammo. He wasn't just being cheap he didn't know any better.

They walk among us, this guy was humble enough to own his mistake and ask for help.

A .458 American will chamber/close battery in a 300 Weatherby easily.

The results would be kinda bad if ya hit the go button.


If you are not actively engaging EVERY enemy you encounter... you are allowing another to fight for you... and that is cowardice... plain and simple.

As a kid I needed 380 Auto ammo and bought 38 Spec by mistake. Store wouldn’t swap so the mistake cost me around $8, which stung a bit.

Don’t think that even possible. Might be some baloney there?

The 270 WBY being a belted case is larger than the 270 Win so it could cycle and chamber, and I can picture the pressure when fireing being blown back into the chamber inbetween the case and the chamber past the bolt and out in front of they action.
Just like water and electricity the pressure will take the path of least resistance.

The 270 WIN case dia at the rim is .470


The 270 WBY case dia at the rim is .540


That is a lot of room when talking 60,000 psi

I managed to do that in a Savage 110. Split case, brass shavings all over the magazine, a hint of blow back on m cheek and glasses, but no damage to the gun.

Just to my ego.

I have shot a lot over the years. I once shot a .308W cartridge from a .30-06 and hit the target just fine. The other time I mixed up a .243W cartridge and shot it through a .308W and the bullet didn't hit the target and the rifle barely recoiled. The .308W cartridge and the .243W cases changed shape but no harm was done.

Had a LGS employee try hard to tell me that I didn't want 6.5 Jap, but rather 6.5 Swede for my grandpa's Type 38. Glad I didn't listen.

Try it sometime and get back to me.

A friend bought a European-looking Mauser-action bolt from Cabelas that didn't have any cartridge markings on the barrel. He assumed it was an 8x57...
Fired cases looked weird - turns out it is chambered for 30-06! Extractor held the case back against the bolt. Amazingly, no damage to him or the rifle.

I gave my nephew a 760 Remington pump in .300 savage. He went to buy ammo, the LGS tried to sell him, .300 Win mag ammo. They said he didn't know what he was talking about. Luckly he is smarter than many young inexperienced people!
