Home Forums Hunting & Shooting Hunter's Campfire Have you ever

Have you ever seen someone shoot a 7mm08 shell in a 270, i have, makes for a interesting day on the range, ruined the shooters day and gun, I did recover the fired shell, new straight wall case, some people just shouldn't own guns

No.

I have just today, even got hit by pieces of his rifle

Seen a Weatherby MKV 270 Weatherby Magnun that a guy shot a 270 Winchester in.
He had borrowed it from a friend. It broke the stock almost into @ the front of the action.
Luckily no one was hurt.

Like Will Rogers said...."some folks shouldn't be allowed to have a box of matches!"

No, and don't want to

Saw 3 .222 rounds fired from a .223. Decent group too.

Two very experienced shooters and reloaders in our club, both past presidents, were shooting multiple guns on the range. Both had Remington 700's in 270 Win. Both also were shooting 308 Win rifles and both shot a 308 though a 270. I am NOT a Remington 700 fan by any measure, however, I must give credit where credit is due. Both guns action locked up and gunsmiths had to un-screws the barrels to get the remnants removed. Upon inspection both rifles were deemed fit and both are still being shot with the proper ammo. Odd things happen. Just last week I was sighting in a friends 270 with Remington factory ammo. One round did not want to chamber. Upon inspection somehow a 30/06 Remington round had found its way into the 270 box. I have heard of old timers that ran out of 44/40 cartridge and instead used 38/40's that they wrapped thin leather around the bullet itself till it fit tightly in the cylinder or chamber. In the NRA museum is a Japanese Arisaka rifle that was used by a man for many years. Common practice after the war was to rechamber their 7.7 cartridge Arisaka war trophy to a 30/06 and never mind about the slightly oversize bore. The owner had done just that and had hunted the rifle for decades, constantly complaining about excessive recoil. Upon closer inspection, the original rifle was not a 7.7 but a 6.5. The NRA doubting the story, fired the rifle several times with no damage.

Wow

A friend did a 280 Rem in a 7mm Rem Mag Weatherby. The floor bottom metal needed to be replaced which I did for him. I was not there for the event.

Having a hard time believing 7-08 in a .270 would blow up a gun. Same sized bullet, .121" difference in shoulder.

I encountered an old timer that wouldn't listen to a know-it-all kid, me. He was not a gun guy but hunted every year. Seeing him shoot his only rifle, a British SMLE, using 303 SAVAGE ammo. I explained to him that both were 303's, they were not the same cartridge. 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.

300 Win Mag fired in a 300 Weatherby MK V.

When the guilty buzzard bought the 300 Weatherby at a local gun shop, he asked for some ammo but he thought the store was asking too much for a box. He went to a nearby Walmart and asked for a box of “300 Magnum”. I don’t know too many Walmarts that carry Weatherby ammo but the clerk found some 300 Win Mag that was MUCH cheaper than the gun store wanted. He bought a box and drove to our hunting club to get sighted in.

A couple of days later I drove to our club to test some loads. I always pick up any fired cases and when I picked up a few cases he had left behind, I thought they looked a little strange ….a Weatherby double radius shoulder but a very short neck. Checking the headstamp, it was “300 Win mag”. DOH!!! 😳

I don’t know how they shot but he didn’t catch too much flak over it. It probably stopped after two or three weeks. 😉

.284 diameter bullet riding in a bore with .270 land diameter?

I can see how it blew up!

.284 vs. .277 is not the same diameter. ... .007 swaged fit is a pressure spiker plus the fire form effect. Stress was definitely there.

Big difference in long and short action to say the least

When they renamed the .280 the 7mm Express I saw a lot of 7 Mag. rifles damaged by the mixup. Remington was quick to go back to the .280 designation.

270 in a 7 mag browning , split case don't know what else ,sent it to midsouth gun and about 400 bucks later it came back ok

As a goof, I retrieved the 300 Win Mag cases fired in a 300 Weatherby and knocked out the primer, installed a new primer, filled the case near full with corn meal, and seated a 71 grain fmj bullet for a 32 ACP into the case. A bizarre looking, extremely short necked, long case with a minacule bullet topping it off. I gave several away to cartridge collectors.

You can shoot 300 Winmag ammo in a 300WBY 7 Remmag in a 7 WBY and use 264 Winmag brass necked down for a 257 WBY. The difference is the loads are lower PSI on the Winmag and the necks are shorter, if you reload the Winmag brass to use in the WBY after 2 or 3 times the brass will flow or grow to the same lenth as the WBY. The brass is not as stout as the WBY so you can't load to WBY specs but it gets you out of a pinch when no WBY ammo is available.

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

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.

We seem to share a common, learned, practice.

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.

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?

I have heard of guys shooting 5.56MM in a 300 Blackout AR15

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.

It happens

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!

Not the same bullet diameter; .277 and .284. Not the same.

Couldn't understand why I had a factory load case head separate in my VZ24 with a commercial 6.5 x 55 barrel until I had a close look at the head marks.

6.5 x 54 MS. Very sobering event despite the fact that nothing was hurt but my sense of knowing what I was doing.

Must remember to tilt my head and use the bottom pane of my trifocals.
