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.

LOLThat there, is some serious fire forming!!
ha ha!Yeah I already returned the one unused box and actually sold the other 10 rounds to a friend, so it worked out.. as far as accuracy, i think it was pretty **** good. was shooting standing at about 150 yards and i got all ten shots within an 8 inch area. Was pleased with that, but after 10 rounds my shoulder was swearing at me hahaThat there, is some serious fire forming!!

Other not, .300 Rem Ultra Mag is flippin expensive...but i can find it online for about $40 a box...guess thats not so bad considering. Anyone know of some places maybe that are cheaper? Thanks!
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!

yeah im thinking the little experiment is over haha
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.
will do! also, i do take responsibility upon myself for part of the error. I definitely should have been more alert to the fact there was a difference between the ammo and gun. I take this as a very fortunate learning experience for the future! I am very excited to own a rifle of this level, and i definitely understand now that it comes with quite a bit of responsibility on my part and vigilance. I appreciate the expertise that you all have and the advice! So I thank you all for that!

With ammo for the 300RUM so expensive, now might be a good time to look into reloading? (if you don't already that is)

Yeah on the subject of reloading that shell, maybe i should start a new thread, but what would i need? Obviously primers, grain, the slug....not sure what machine i would need. Also, what kind of life expectancy can i get per shell? I hear some dont like to reload the ultra mag brass more than three times because of the power?With ammo for the 300RUM so expensive, now might be a good time to look into reloading?

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!
