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!

Wait a minute, something is not right. Your gun is marked .300 REM ultra mag, not .300 WIN ultra mag. There is no .300 WIN ultra mag that I am aware of.
Post a pic of your fired cases. If you had shot .300 Win Mag cases in a .300 Rem ultra mag chambering, they should come out looking nearly straight. They certainly wouldn't look like they did going in.
Need more information.

That there, is some serious fire forming!! 
I'd think you quite lucky that nothing worse happened and as already mentioned I'd highly recommend you do not fire any more of those incorrect rounds in your rifle.
I would also call the manager or owner of that store and tell them of their terrible mistake. I'd further insist on a brand new box of the correct ammo to replace the incorrect ammo which might have caused you some serious harm.

Wow, you are right. Never seen that kind of fire forming before. Glad you weren't hurt
How was the accuracy out of those loads? Just wondering? Scotty

Holy CRAP !! Thankfully your fine. Never seen anything like that before. I agree with what the other guys are saying about calling the manager or store owner if it's a mom and pop kinda place. Give Ammoengine.com a try as well as Midway USA and Natchez Shooters Supplies. The ammo engine website is a pretty neat site, you pick your caliber and it will list whatever is available in order from the cheapest to most expensive. Good luck to you
Normally when you fire a case into a grossly oversized chamber, the pressure goes down. But not always. I'm surprise that none of the brass ruptured - good thing it was new and not old and brittle.
Fascinating little experiment, but don't be in a hurry to repeat it!

I took it in to get looked at this morning and picked it up this afternoon, thankfully no damage to the gun whatsoever! I also got some 300 RUM managed recoil 150 grain for $35. From what i've found reading around, the performance of managed recoil is still incredible as compared to a normal round. They had it listed for $40...but they gave it to me for a bit less which was good.
With ammo for the 300RUM so expensive, now might be a good time to look into reloading? (if you don't already that is)

Start with a good current reloading manual. I would suggest the Lyman 49th edition. This book has good basic instruction for beginning reloaders and also has several loads for your 300RUM. And go back to the forum section on handloading equipment and read the threads. Much good advice for newbies. Good luck.
PLEASE!
May I have one of those expanded cases?
I am a firearms instructor and that would be a valuable tool in my classroom. I promise not to name names, and that lots of people will benefit from your fortunately noninjurious experience.
You should be able to PM me through the forum.
Thanks!

Unfortunately i've already given the old brass away and kept one for "a little reminder". Otherwise i would have gladly sent some around!
In the end I am going to keep the gun, and get something else as well. After all I got the thing for such a dirt cheap price that i really dont consider it all that much of a loss if i shoot it every so often.
As far as reloading, i have a friend here at work who hunts with a 300 Win Mag and a 300 RUM...and he's been reloading those shells for years. So I think he is a perfect resource. Im actually going over there tonight and we are going to make some, and do some training...pretty stoked!

WOW. You are so lucky your still alive and or have all your hands intact. You might want to look into a muzzle brake for that also it will help soften up the punch.

Neat picture. What kept the problem from getting out of hand, in my opinion, was that the bullet was probably reasonably well aligned in the throat when it went bang. And of course was the correct diameter. If the bullet doesn't get stuck, then the gas pressure just expands the case to fit the chamber.
The rifle manufacturers have to design the gun to handle a certain level of escaping gas, because case heads to let go from time to time. When pressures get pushed outside of the normal range (due to a bore obstruction or delayed ignition, etc.) is when bad things happen.
Thanks for posting the pic. Good lesson for all.

Very interesting event, and nice symmetry on the olives. Hope you have someone to help you out getting started on hand loading. You can find out anything you need to right here, but a hands-on instructor is unbeatable.
Yeah i've started reloading at this point and am trying a few different loads. Thanks to Hodgdon and their reloading data center, im going to try a few things. I bought some Hornady 180gr Interlock BTSP's as well as some SST's. Powder im using is Retumbo, with min to max grain 94.0-100.5C. So im going to start experimenting with different loads and see what I get. I also want to try some nosler accubonds. maybe some H1000 powder...
oh and side note, boresnakes are the best thing ever when it comes to cleaning the thing

I would bet that Retumbo or RL25 would give you excellent speed and accuracy. I would be a little weary of pushing unbonded bullets at RUM speeds, but heck, if you are just hunting deer with them, I bet you would be okay. Be too look into some AB's or Interbonds, just for some extra insurance! Scotty
