I know I guy who fired a 270 in his 7mm RM and got his face bleeding from blow back gas and powder through the bolt, I wouldn't suggest trying either
What would happen if you touched off a .308 in a .30-06 chamber?

I'm so wealthy and I love to burn money on absolutley pointless experiments so I'm quitting reloading and gonna start buying and shooting .300wsm in my .300wm.... Not. Now in all seriousness if I'm some sort of a hypothetical emergency
what can be chambered and fired in the .300wm? So far I gather .300wsm and 7mm rm?

WSM likely won't chamber in a 300WM. The WSM case is larger diameter.
Many of the belted magnums would chamber in a 300WM, though.
Well I suppose I could just get out the old manual and do some reading or try measuring/chambering some fired belted stuff. I honestly don't really see too
much of an issue as long as it's reasonably new brass and tight enough in the chamber to align with the bore. More likely to get a bullet stuck in the barrel than anything else. The brass takes relitively nothig to fire form so your basically dealing with nothing but light powder charges. If the pressure is great enough to seal the chamber via case expansion your all good, since it's common place to fire form with light charges topped with cardboard or wax plug.. I'm sure sealing the chamber is no issue. If one were to choose, I would expect belted chambering would be the safest if one were to play such game nthe belt would ensure decent headspace to prevent light primer strikes and minimize chances of head seperation. Also when you take this full size chamber
designed to fire xx grains of powder and contain xx ###psi then you subtract 5,6,7,13,19grains of powder, your going to be dealing with substatially
less chamber pressures yet still being contained by what in effect is only casing missing it's neck and we all know that cracked necks don't cause any dangerous gas leakage. As another factor, since pressures rise progressively with the addition to each kernal then then pressure will also decrease digressively with the subtraction of each kernal. It would be interesting to see if there is any pressure data on these types of accidents. I suppose if someone were to plot pressure vs velocity beyond the minimum book listings then chrono'd some 308 in 30-06, wsm in wm, you could get some satisfactory approximations. I'm betting pressures are 1/2- 2/3 what the bullets original designation and half what the rifles designation.

Is This Question For Real?
I read this particular question and two immediate thoughts struck me. Either Fuzzy is trying to be whimsically farcical or he should not be allowed to own a firearm because clearly, he has been influenced by too many hours in front of the X-Box. Pray tell, what would this "emergency" entail that would risk such a stupid-ass question?
He had better not be thinking Zombies or such other foolishness. If he is serious...that is scary

!I don't doubt you gatehouse. I just assumed it was little else than a shortened version with a different shoulder angle. Learn somethin every day. Hopefully that's the only thing I learn today.... I thought I knew everything. I'm gonna do some investigating as until I read this thread it never occured to me it was possible to do it safely (well I can't realllllly say safely but...) it's still good information to know what you could do if you had to, and I don't mean if i forgot my bullets so Im just gonna use my pals in my gun. I mean a griz is running down on us fast, my buddy jammed his barrel inthe ground so I've shot all mine and his gun is out of commission, can I use his bullets.......
Sobo, I don't play video games, I don't even watch sports on tv or even in person. I spent nearly every moment I can in the bush one way or another, dirtbiking, hiking, shooting, looking for furry creatures, sledding, prospecting.... You name it. I have zero interest in shooing anything but my own handloads in my rifle, however I like to know every angle on every possibillity, I don't take "cuz I said" as an answer... You cannot fault me on that. Now I'm not foolhardy and will use such possibillitys to be careless since I "may" be able to chamber and fire a different type bullet but I would like to know what I could if I HAD to. I just simply like to know everything about everything, learning has consumed me, not x-box, hot rods, guitars, jersey shore... If I'm not with doing some bs with my gf, at work or in the bush I'm readig, experimenting and learning, simple as that.
Clarification Accepted
My apologies for my reaction, but honestly, I wuz reading the thread and then boom! That question right out of the blue. You gotta admit, with all the experience you have, that if you had read that in a wee bit of a different context such as I did, you would not want to be in the same County with someone with a gun whom appears to be so goofy. I always carry spares (bullets) for spares. One for animal, the rest if I get into trouble.
I actually had to use them all once to help a stranded inexperienced hunter after dark find his way back to the road. Used all but one (about 19) of the rounds I packed with me to get him out safely.
But when I read that particular question, I thought, "oh man...this stuff is serious for some zombie shooting x-boxer. Which of course, I now know was a patently wrong assumption on my part.
Cheers!

No prob sobo. I did take a little lookie look through the old Sierra book lastnight to see what would chamber in the .300wm The only
candidates I found are .308 Norma
magnum which I've never seen a
rifle or even a spent casing for, it's quite similar, but the web area may be too tight and the 7mm remington magnum which I would expect be completely
usless for anything but making noise. You'd be better off flinging the bullet with a spoon.

no....I know from experience and still hunt with the gun...A BSA monarch in 270 Win that I fired a 308 Win 165 grain thru.....case looked like that 308 case but pressure signs and blow out primer.
gun shoots good to this day...shot a buck with it the next week.
it is a whole lot easier to #### up then most of you give yourself credit...really.
A few years back I went to the range with my 30-06 and my 308.
All my ammo was in green plastic boxes. I was getting ready for moose season.
I sighted in my 308, no problem.
I grabbed another green box of shells, thinking that they were 30-06. They were 308's.
I put that in the 30-06,[Rem 700 BDL.] and pulled the trigger. What a hell of a noise. when I ejected the casing the whole front was gone and the primer was blown out. I scared the hell out of me. Not only did I do this once but twice. Lesson to be learned don't take a 308 and a 30-06 out together.
I CAN HAPPEN TO YOU. I sold my 30-06 not too long after.

I just placed a model of a 30.06 over a model of a 308 in Solidworks and as far as I can tell, they run at exactly the same angle. So the 308 would be pretty much encased by the chamber walls all the way up to the shoulder. That make any sense to anybody?
It takes a sloppy 30-06 chamber and a minimum size .308 case to be able to chamber it.
The .308 case is fatter at the shoulder than the 30-06 case is in diameter at the same location.
If you manage to chamber a .308 case in a 30-06 and fire it, I would expect all that would happen is the bullet exit the barrel and the case formed out as pictured above. I doubt you would have a case separation or gas leakage.

I have a .308 case that was fired in a 30-06, picked up a couple at my range MVRRC, wondered WTF. When I went in the clubhouse to sign out they had one with a letter explaining what happened. The neck is missing off them, not sure where the necks went or why they kept on shooting but it's a true story. I have a case to prove it.
