Just bought a Savage Arms Model 116. takes a .300 Win Ultra Mag. When i bought it, the ammo they sold me was .300 Win Mag. So of course being all excited to shoot the new gun, took it to the range and took care of ten rounds. They loaded in just fine, chambered, fired, and the case ejected just like a text book case. Afterwards, i was looking at the casings versus an unfired round, and they had expanded ever so slightly. Hence why i am posting on here. Is it ok to continue firing these rounds in this gun? Thanks!

NO!
Not until you find out what caliber it is anyway.
The first thing you need to do is read the caliber marking on the barrel.
It can't be a Win .300 Ultra Mag, because there is no such caliber.
There is:
A .300 Win Mag.
A .300 H&H Mag
A .300 Rem Short Action Ulta Mag, or .300 SAUM.
A 300 Win Short Mag, or .300 WSM.
And a .300 Rem Ultra Mag.
But there is no such thing as a .300 Win Ultra Mag.
I beleive it is very likely your rifle is in fact a .300 Win Mag, as that is the only .30 cal magnum Savage chambers them in currently.
The differance in fired case appearance is due to normal case expansion when the case blows out to fit the chamber.

Well, that's what you need to shoot in it then.
Do not fire any more of the .300 Win Mag in it!
The .300 RUM does not have a headspace belt on the case, and the .300 Win belted case is smaller then the rear of the chamber in your rifle. That will allow it to chamber, but headspace would not be controlled at all except by the extractor.
You are lucky you didn't blow yourself up already.

Please post some pics of the fired cases beside loaded cartrigdes. I would like to see them.
Thanks!

If you only buy the ammo whose caliber, printed on the box and on the case head, matches the name on the barrel, you won't blow things up or harm your equipment. This is an IQ test.

Mr. Harry, I think the above is a good, useful statement. The rest of your post was not useful.
I know now not to trust the guy who sold me the ammo...I'll post pics when I get home from the day. Just interesting how it safely shot, and accurately, 10 rounds of win mag. I'm definitely returning the unused box and getting the correct ammo.

How close is the scope to the barrel??? In the pic posted it looks pretty close.

yeah...Don't do that....that can't be good for your health if you keep doing that.
Don't hesitate to slap the guy that sold you that ammo. A competent gun store employee should at LEAST have enough snap to him to read what's stamped on the barrel, while a good salesman period should know about what he's selling.

just curious but did you buy this rifle/ammo from a large chain store or a small gun store?
I can see (and have had) this type of thing happening at say walmart or gander mountain where they need nothing more than an application to work there
if it was a small time gun store I certainly would do my own homework on anything I buy from them before ever even thinking of purchasing that way you negate the miss information they can obviously provide

mwurman,
Your rifle is a .300 RUM (Remington Ultra Mag) the .300 RUM is based on a .404 Jeffery case that's been necked down and reshouldered.
You fired a .300 Win Mag through it. The 300 WM is a smaller diameter case and a shorter case by almost 1/3rd of an inch.
Notice how the case has expanded in diameter just forward of the belt. That expansion reveals the actual diameter of the chamber vs the much smaller diameter of the case you fired in it. The original diameter of the .300 WM case is the diameter at the case head (the back of the case).
Ditto on the shoulder being blown out to match the RUM dimensions. I honestly don't know how that action was able to seal up and not allow the explosive release of hot gases into your face.
YOU ARE LUCKY to have not lost an eye at the very least.
You need to rush back to that gun store and speak to a manger immediately. He should repair and or replace your rifle. And fire the dim wit who sold you that ammo. I wouldn't fire that rifle until it's been looked at.
It's hard to believe that thing was even able to fire. Once again, you've got a guardian angel looking over you my friend don't tempt fate twice.

I wholeheartedly agree with H&Hhunter. I'd also like to say that God must really like you, because you're still breathing.

What brand is the ammo that you "fire formed"? That is some really good brass not to split!

Frozen North just voiced what I was about to ask...
THAT is some serious stout brass.
Brother, you are lucky...no kaboom and hopefully no rifle damage...I would get a smith to at least take a look at it.
