Need your advice guys. I accurized a Win 70 pre 64 style action in 300wm for a buddy. He bought a box of ammo the night before. At 4am he loaded his rifle. He saw a little buck and took a shot. The gun just clicked. He jacked another shell and this one went off. He got a little blast from the pressure port, but thank God it only left a dime sized scuff under his eye. Come to find out, he had loaded a couple of 30-06 shells in the gun and fired one. Funny part, it hit the buck and killed. Weird, but true.

Now, can this gun be trusted again? Can I do a simple visual check after tearing it down? o I need to scope the bore and chamber? Advice please.
 
Re: Shot 30-06 through 300wm Accidentally

Good that everybody is ok and an outstanding kill. That is gonna make a good story for the grand kids someday. I would load a hot round of 300 mag and tie off the trigger to about a 8 foot string and pull it. If the rifle is ok then I would proceed without worry.
 
Re: Shot 30-06 through 300wm Accidentally

Rifle will be fine. That won't hurt it a bit.

Check the barrel/chamber/etc. for fragments of casing. There should be no problems w. the barrel. Check extractor to make sure it did not get sprung... But my guess is that the rifle didn't even notice.

Love to see a picture of the extracted case, though.

Cheers,

Sirhr
 
Re: Shot 30-06 through 300wm Accidentally

He's lucky it wasn't a 7mag.

Honestly, if he doesn't know the proper ammo to fire in his rifle, he probably shouldn't be shooting it. Pretty careless on his part.

rifle wouldn't have noticed a 7 mag as much as it did the 06.... might have had to scrub the bbl, but that's about all
 
Re: Shot 30-06 through 300wm Accidentally

He didn't keep it. He was too worried about his face
smile.gif
He said the case looked like someone took a grinding wheel to the side. Glad to hear the gun will be ok. I have some hot 300wm I can throw through there and a long string too. Thanks for all the advice guys.

He said the ammo was from the new box he had just bought from store the night before. He didn't think to make sure it was all 300wm since it was off the shelf.
 
Re: Shot 30-06 through 300wm Accidentally

I'd say the gun is fine. It's not like it overpressured. If anything it was way, way down on velocity due to the cartridge ballooning up like it did. I'd look the bolt over good and make sure the gasses didn't erode the pin or anything else.

Glad he's not hurt and that there's meat for the freezer!

Aaaah, jeeeeerrrrrrkkkkyyyyy.

Maybe he meant shooting a 30-06 in a 7mag chamber? That might get you some pressure.

Is this kind of thing why rem receivers have that hole drilled in the side just behind the barrel threads?

Absolutely. It's called a "gas check". There's a couple ways to do it, but that's one of them.

Many of the better custom actions have a gas check (or checks) on the bolt body as well. The pressure will blow past the striker and pressurize the bore inside the bolt body. The vents (checks) allow this to vent to atmosphere so that you don't eat a plume of gas as it wiggles past the cocking piece/shroud.

The pressures inside a rifle are not to be taken with a trivial attitude.

Hope this helps.

Re: Shot 30-06 through 300wm Accidentally

Just had a customer do the same thing. Complete case head separation, gases cracked the stock and bent the floor plate. I popped the "fire formed" case out, checked the bolt, firing pin, headspace, took a look in the chamber/bore with a scope, cleaned the bore, repaired the stock and test fired the rifle. Other than the busted stock everything is back to normal.

You got it! Make sure you never let it get clogged with dirt/bedding compound etc etc...

Also, never truly "trust" that port...just like you should never trust your safety.
 
Re: Shot 30-06 through 300wm Accidentally

Great info guys. I was kinda sick when he told me, but I was VERY happy he didn't get hurt.
 
Re: Shot 30-06 through 300wm Accidentally

Nah...look up some of the stuff the Feds did back in the '30s. They shot every conceivable cartridge that they could get to chamber through the '06 without failures. Since they had a controlled round feed model...a 1903...even a .45 ACP. (They did relate, that it was a funny looking long bullet when they recovered it.) 8mm in the '06...no problem. 7x57 mm...no problem. No accuracy either. 30-06 in a 7mm mag chamber...ruptured case, maybe, but possibly just a lengthened bullet...and a severely deformed case. JMHO
 
Re: Shot 30-06 through 300wm Accidentally

I watched a guy chase a zero with 4 boxes of ammo before I was compelled enough to see what he was doing wrong...4 boxes of Federal premium 300 Win mag through a 300 Weatherby Vanguard, accuracy sucked.

That's good to know. I've heard before that you can't damage a '03 no matter what you stick in the breech. I, in fact, accidentally shot a .308 out of my 1903-A3 once with no noticeable difference until I ejected the case and it looked like a .45-70

The good Springfields are ungodly tough but some of the early ones were very brittle. I can't remember the serial number range for the bad ones.
I used to hate drilling and tapping those things for scope mounts. I would have to spot drill through the skin with a single flute carbide and then drill the remainder of the hole. I would try to spot anneal the holes before tapping by inserting a tig tungsten in the hole and cooking it, but I still got plenty of experience in removing broken taps.

Funny that the OP's story still killed the deer... what I find even funnier is that he's claiming

"Didn't look to see if the new factory box of ammo was all the same cartridge"

Re: Shot 30-06 through 300wm Accidentally

I've got a couple of .243 shells that I fired from a .270 years ago. My little brother and I were both shooting Remington Core-lokt ammo, and in the heat of chasing a herd of hogs I grabbed the wrong box when I reloaded. Fired twice before I noticed the now fire formed shells. Never noticed any damage and I still shoot that 270. Now we have a different colored MTM box for each caliber.
 
Re: Shot 30-06 through 300wm Accidentally

A group of us from work went to a pistol range one evening. One fellow had both a 40 cal of some flavor, and a Colt New Agent 1911 - thus he had both 40 and 45 ammo on the bench. Another coworker asked if she could try out his New Agent...

We didn't notice until AFTER she fired an entire magazine out of it she had been firing .40 cartridges through it. That's right... The magazine held .40 cartridges, the pistol fed them, the extractor held them in place well enough to fire them, it cycled, and honestly....her group was about as good as it would have been had she been firing the correct ammo.

This told me that if I were really in a pinch, and all I had was a 45 pistol and 40 ammo, I'd give it hell.
 
Re: Shot 30-06 through 300wm Accidentally

Crazy thing is, I just went on my annual deer hunt with my friend and his dad and found out he had fired a 270(I think it was) through his Ruger #1 7mm he got from us for Christmas last year. It broke some internal parts and split the stock. He replaced the internals and glued the stock, but the thing shot about an 8" group of 3 at 100yds when we shot it this weekend. It might need some more work

Re: Shot 30-06 through 300wm Accidentally

I fired a .22mag through a .22lr once. That was a close one!
smile.gif


Serialously, glad no one got hurt.

These stories are always a good reality/safety check.
 
Re: Shot 30-06 through 300wm Accidentally

Had a customer two years ago that had two 7400's, his and his Dad's. One in .308 and one in .270.
The .270 snatched up the .308 round he put in it, and the extractor held it for the firing pin to make contact. Brass body was the size of the .270 chamber and the case head was permanently attached to the bolt face, but the bullet made it down the barrel and it didn't blow up, I figure the gas port bled the pressure off.
I deemed it 'unsafe to fire' for liability's sake.
 
Re: Shot 30-06 through 300wm Accidentally

Question.

How does one 'retire' the aftermath of something like this?

Really? How exactly did you accomplish that? Please explain.

I will help you a bit. Did it involve a hammer at any point in the chambering process?
I say BS.
You may have shot a 22LR in a magnum revolver cylinder but you did NOT shoot a 22Mag in a 22LR chamber.

While accuracy would have suffered, that is not unsafe condition. The cartridge would have headspaced correctly on the belt, but the bullet would have had a long jump to the lands...... The cases would come out with essentially no neck.

I've seen this happen before too. I've also seen 9x19mm rounds shot through a 40SW barrel. No case ruptures but some interesting cases and less than spectacular accuracy. Not something I'd recommend but an option in a survival situation.

The 9mm through the 40SW is actually pretty surprising to me, can't believe that the extractor would capture the rim enough not to just push the whole round case and all out through the barrel. When I got my 40, I took a 9mm snap cap (didn't have any in 40) and fed it into the breech to see if it would lock up. I laughed as it slid freely through the entire length of the barrel and fell to the floor when I let it go; went on amazon and bought some 40SW snap caps right after.
 
Re: Shot 30-06 through 300wm Accidentally

Was on the range one day when someone accidentally loaded 40S&W into a 45ACP pistol. He had this odd habit of charging the pistol, pointing muzzle at the ground, raising muzzle to target, aligning sights and pulling trigger. First time it happened there was a click. He pulled the slide back, nothing came out. So he closed the slide, went thru his "ritual" again and, you guessed it, click but no boom. This time I decided to watch closely. When he pointed the pistol's muzzle down something fell out the end of the barrel. Yup, it was a 40S&W round and there were three on the ground. Glad nothing got stuck in the barrel.

Re: Shot 30-06 through 300wm Accidentally

The 300Win mag in a 300Wby chamber thing must happen a lot.

I had a buddy growing up that used his dad's MkV for hunting. One day we were driving back to the house and I noticed these funny looking empty cases on the seat. They had the Weatherby double radius shoulder but the necks were only maybe 1/8 inch long.

I thought what the hell is he doing to these cases until I looked at the head stamp. Yep, sure enough, they were 300 win mag. I asked him why the hell he was using 300 win mag shells in his dad's 300 Wby. He told me the Win mag stuff was a lot cheaper so he just bought that instead of the 300 Wby stuff then proceeded to tell me it shot just fine. I asked him if it shot so "fine" why did he already have 1 1/2 boxes of empties and no deer.

You hit the nail on the head there my friend. Last time i went with someone else, his superblackhawk 44 threw the ejector rod at me from a over charged reload.

Re: Shot 30-06 through 300wm Accidentally

OP, I'm a bit confused. You said he bought a couple boxes of WM the night before, loaded from those boxes and ended up with an '06 in the chamber. Did I miss a step or was the box improperly labeled? If so, keep the case, take photos and call a lawyer.
 
Re: Shot 30-06 through 300wm Accidentally

If you're real concerned about the structural integrity of things, there are a bunch of ways to check for damage:
Dye Penetrant
Magnetic Particle Testing
X-ray
As well as a few others, jut do a search for NDT - non destructive testing.

While I'd want to keep the action/rifle too, the question of it's integrity would always be on my mind, unless I had things fully checked out.
NDT is cheap compared to a trip to the ER.
