What happened to this brass?

[imartin]

It sure dose looks like a 300 Win Mag fired in 300 Wby Mag alright. Overall length on a 300 Win Mag is 2.620, and 2.825 for a 300 Wby Mag. The shoulder lenghts on a 300 Win Mag is 2.356 and Wby Mag is 2.384. Note the difference from the rim to the belt. Somebody got mixed up or something. Anybody look at the head stamping on the case's?

I am not for sure on the 30/06 cases, but they look to be a head spacing problem.That rifle needs to go to a gun smith.

You can covert several case into other cases, but you have to full length resize the case to start with. Trim to length and other work. 30/06 case can converted to 308, 270, 25/06 cases. The Winchester Mag case can be converted to be used for anything from 338 Win Mag, 300 Win Mag, 308 Norma Mag and 264 Win Mag. There is some work involved to complete the case change, but it works. Don't say that can't be done. I covert 300 Win Mag cases all the time into 308 Norma Mag cases. Buying 308 Norma Mag cases are very expenses and 264 Win Mag case can be a little prices too.

Go to your hand loading manual and look at the different on those cases that I have stated above!

Use 7mm Rem Mag for your 264 Win. Should be a lot easier. Idk enough about the 308 Norma to offer an opinion.

I saw a guy doing that at the range, he would cut the shell almost all the way around the base with a hacksaw blade then shoot it. It was hitting the target and punching a 1" hole in paper at 50 yards like a slug but it was #7's. Not sure what choke he had but I moved to the other end of the shooting line.

This was very common 50+ years ago when guys couldn't afford slugs and only bought one kind of shotgun ammo for everything from rabbits to deer. In the Adirondack Mountains it was called a hillbilly slug. Some guys used a pipe cutter to get perfect cut rounds so the wad and upper half of the round went perfectly with the shot downrange like a slug. I saw it done with old single shot HR and made sure I was way behind him when he shot. Effective "cut round range" for deer was about 25 yds he told me. Nope, not even dreaming of doing something that crazy. Stuff like this ends up on the Darwin Awards page:

I was at a club for meeting yesterday and found these 4 cases on bench. They are FC 300WM but what happened to the neck of this brass? I think they were shot in something other than a 300WM like a 300Wby? Thoughts?

Absolutely zero doubt in my mind that they were shot in a 300 Weatherby. The shoulder angle tells all. No other cases that I am aware of have the rounded shoulder angle Weatherby uses in it's brand name in house designed cases. More important however, were five rounds fired and four were left as the shooter took off for the hospital?

Where was the bullet ?

I have a couple 25/06's. The one thing I found is you have to be careful about case length or seem to be anyway. Case length is 2.494 in a 25/06, and 2.015 in a 308 winchester case. The 308 Winchester case is to short to load for a 25/06. Doesn't anybody look at their reloading manuals to see what's what's? 220 Swift case length needs to be watch closely too.
I have over dozens reloading manuals and buy more over the years. One to get info on new rifles, and new powders. I fact I have a Hornady manual that printed with the outside jacket upside down and back words. I am wondering were they 308 caliber bullets to start with. I would think the rifle would blown up and the bolt came back into the shooter face.

Good news was there was no blood or other tissue on the bench so I am hoping after 4 rounds of something just not right got their attention. I am donating the cases to our hunter safety instructors as perfect example of what not to do.

Maybe this is just an improvement over the short neck of the 300WM to reduce neck tension?

Don't think it would have enough tension left to keep the bullet from falling out!

Where was the bullet ?

Bore was clear. Barrel measured the same as another factory 25-06 barrel inside and outside. Barrel was replaced with a new one. Only marks on receiver was where the jammed extractor rubbed when opening the bolt. No marks or indentations from bolt lugs.

I didn't read through all posts yet but it also looks like a separation starting below shoulder on all four ?

I had something similar and odd happen to me. I bought a bunch of 300H&H ammo a while back from gun shop that sells older ammo. The bullets I got were stamped with 300H&H and looked identical to all my other rounds, but when I tried to use them, I couldn't close the bolt. Odd but I am at least smart enough to not force it....

I have a 300 H & H mag also. I am thinking two things. Case length is to long or size up to 375 H & H mag? Thinking they were 300 H & H Mag loads due to head stamp. I have used 30/06 case to resize to 270 and 25/06 cases. I use 300 Win Mag case and resize to 308 Norma Mag case. Don't mistake that for a 300 Norma Mag either. There is a lot of changes done over the past few years on different rifle cases and loads. So now it even more important to take care of what somebody is handing you. What becomes very interesting is I load for my two sons at time and they have 25/06's and 308 Norma Mag too. All chambers are not the same either. Once the case if fire formed to that rifle it generally won't go into a different rifle. So special care has to be taken to not mix up the cases when loading for different rifles.

I see that I am going to have to get some new manuals, because the one's I have don't show much of the new loads that are out.

Had a similar experience on an elk hunt. Another hunter had a 300 wby and I saw him grab a box of of shells before the group headed out. He missed an elk and the guide had me go with him to the range. He fired one round and I asked to see the shell. Attached is what I saw. Needless to say we went to a sporting goods store and got him the right ammo.

I remember when I was a kid (70's-80's) that there was this recurring idea where it was said that one of the benefits of the 300 Weatherby Mag was that you could shoot 300 win mag ammo in it if needed. Almost like you were shooting a .22 long rifle and could shoot 22 shorts in it with both being ok. I heard it multiple times from multiple sources. I think at least to some degree it was something that was passed around incorrectly among some shooters. Now, these sources were just local gun guys who thought they knew everything but didn't, not real gun experts. And we didn't have the WWW to go look stuff up on. But I think it brings up the point that some folks did and probably still do think it is perfectly fine to do that. Do a search on Google and look at how many results you get of people wanting to know if they can shoot 300 win mag ammo in their 300 weatherby. I think it was, and to a degree still is, a fairly wide spread misconception.

I have never seen it done in real life. But there you go, obviously it will work at least a few times. I bet it grouped really nice with that 1/2 inch jump.

By looking at my books, that is exactly what this is.. 300 W/M fired through a Weatherby chamber. this will be a pain in the butt to reform.

Have to share this one: for years I only shot pistol, mostly IPSC back in the day, but I'm also an NRA and CA DOJ Certified Instructor in Basic Pistol, so most of my range time has been on the pistol side.

One day this guy shows up with a beautiful Series 80 1911, factory nickel plated, looked brand new, but I'm guessing it was from the '90's. He has a lot of expensive equipment, but he's loading the pistol out of a plastic sandwich baggie.

Fires one round, struggles with the slide, finally ejects the brass, fires, tugs and fights with the slide, finally ejects the brass, repeat, over and over, at least a dozen rounds.

One of the ejected rounds lands at my feet: a .40 S&W case split back to the case head. I ask, "Is that Colt chambered for .40 S&W?" Mr King $hi& responds with a sneer, "Of course not! All 1911's are .45 ACP!" (Not true, but I let it go.). Me: "Then why are you shooting .40 in it?"

At first he denies it, but I hand him the split brass. He looks at it, but doesn't acknowledge he's done anything at all unusual, but IMMEDIATELY starts up, like I knew he would, talking trash about my 686, Model 19 and Model 29 Smiths: "I wouldn't own a S&W! I own THREE Pythons, AND a Diamondback! I own a Korth revolver! I have a Colt National Match 1911!" And on and on. Mr. Expert. Yes, I'm a dumba$$, but I (think I) have more expensive guns than you.

Me: "Do you shoot .40's in that National Match too? Or .32's in the Pythons?" LOL! What a doof. I looked and his plastic baggy contained loose .45 ACP, .40 S&W and 9 mm rounds, and he would just reach in and grab a handful.

All those fine pistols and revolvers, and no money for a cheap MTM ammo box. Like I said, they're out there.
