well shot the mosin today and =(

[jeremyb]

WOW! 515rounds thats a lot of ammo through a MN in one day.

I wonder at what point will the heat damage the gun? Mine gets pretty hot after a lot of rounds in 90 degree weather. Should this be a worry?

That is why you take more then one gun with you to the range. Your accuracy will get worse with heat likely. Maybe 10 from 1 then 10 from the other and so on

Thats what I have been doing. I only shoot two at a time--so I only have to clean two at a time.

....... Those war time barrels just get too hot too fast due to the lack of quality which was sacrificed for volume. Now don't get me wrong she shoots straight but she will take four hours to cool down after two boxes. My older ladies don't heat up like that until 200 or more rounds. .......

I do not see how that is possible. the quality that was "sacrificed" was in the finish - not the amount of steel in the barrel.

The speed they heat up and cool down has to do with the mass of steel, and the heat transfer coefficents of the metal and wood plus the convection currents of air passing over the stock and exposed steel. None of that would be significantly different in the two vintages of rifles. If anything the rougher surfaces of the wartime metal would act as fins and possibly transfer heat to the surroundings a little better but the difference would hardly be noticeable.

Also I have shot 4 boxes of ammo through a war time Mosin and it was so hot that you could not touch the metal and cosmoline was oozing out all over the place but it cooled down enough to comfortably touch the metal in about 15 to 30 minutes.

video or it didn't happen

[ber8860]

no one was drinking at the range OK it "it was beer A friends uncle had bought and he didn't like it. was those tall cans. And yes it was roughly 500 rounds, but could all that shooting have damaged it?

[desdem12]

I am almost sure your brain is already damaged. I doubt if shooting 500rds will hurt you anymore then already.

[Junk Yard Dog]

Ask the Mosin kid what overshooting a Mosin will do to it, he had a nice laminated stock, but he don't no more.

Really.. Melted the glue?...

[ber8860]

alright so the worst taht gets damaged is your stock get scorched and finish melts off

No, the worst that can happen is that you severely burn your hand by touching the hot metal.

BTW the person with the laminated stock said that the stock warped - not that it was scorched.

I <3 this thread.

[Groundpounder]

I have an 11 Bravo granted immunity to recoil, but I've noticed something weird with the Mosins. Shooting standing unsupported I end up with a bruise between my bicep and my pec right in the dead spot between the two muscles. I know I'm not letting the buttstock slip out, but this thing looks like I painted it on with a magic marker, Think of what those steel corners would do to a Nazi skull...mosins are dangerous at both ends.

No, the worst is that you will have damaged a piece of history through incompetence and general stupidity. The kid didn't know what he was doing because he lacked experience with firearms, you on the other hand have been told. Other things can happen as well, heat the chamber up enough and you could cook off a round, that's when a round detonates from heat rather than you pulling the trigger. Best case the weapon is pointed at something inanimate when it goes off, at worst the round hits someone, kills them, and you spend the next five to fifteen getting sodomised by Bubba on a nightly basis. These weapons are also older than most folks parents, or grandparents, in your case great great grandparents, it is unwise to put extreme stress on metal that old, you can live without a kidney, a lung, eyes, balls, arms and legs, but not without a head, and that's were the bolt is going should that receiver let go.

We have had ultrasounds done on the barrels of the later war time barrels and have found inconsistencies. Essentially the metalurgy due to the rush to get rifles out isn't as consistant thus sacrificed quality. Granted that being said my '42 Izhevsk's barrel is still better than the brand new Remington 770 I received a a gift. It amazes me that in a crisis during a war the Russians built a better barrel than the Turks do for Remington with today's modern equipment and newer techniques. I trust all of my mosins before this Remington but the point is my '42 gets hotter and stays hotter longer than my other 3. Perhaps she does not like the heat an humidity down here in Houston or the heat we had in Dallas but she has been relegated to primarily winter use because of this. I freely admit I am still learning and can only comment out of my personal experiences but when you look at 35 rifle '42 and younger and see inconsistencies in all of them that you do not see in the older rifles a bit of quality was sa rificed in favor of speed. It's still better than this blasted Remington. I'd get rid of it if it had not been a gift from my parents intended to be given to my daughter as she gets older with express instructions of break it in and rework it for her. I will still be getting her a Mosin ASAP!

[Junk Yard Dog]

I never had this problem with my '42 or any Mosin, but as a rule I never fire more than ten shots out of any rifle without giving it a cooling off period while I go shoot another Mosin, or my .22. I do this to avoid heating the stock to the point that cosmoline will start seeping out of the forend taking shellac with it. I don't spray and pray with the ten shots either, that will also cause rapid heating and ammo is too expensive to waste. Mosins will heat quickly, heavy cartridge, thin wood, this goes for any .30 service rifle.

I don’t dispute that there may be metallurgical differences in the steel but that would not make any significant differences of the heat transfer and retention properties. Below is a table of the heat capacity of several metals. Notice there is only a small difference between cast iron and carbon steel. The differences would be a lot less than that for slight variations of the carbon steel.

Anyway, by far the strongest factor controlling the speed of heat up and cool down of the rifle is the way air flows over the stock and exposed metal. Second to that would be the insulating properties of the wood. The metal properties have to be considered but are much less important.

I can understand that it's probably a good idea to not shoot off dozens and dozens of rounds without letting the gun cool off, but I honestly find it hard to believe that anyone can fire off enough rounds from a Mosin quickly enough to get the chamber hot enough to detonate a round. I would honestly have to see that one to believe it. Whether you use stripper clips or manually insert rounds, you can only put in five at a time, and that in itself will give the chamber and barrel a little time too cool. I just can't see this happening with a Mosin. An AR 15 with a 100 round magazine, maybe, but with an old bolt action clunker like the 5 shot Mosin I think this is very unlikely.

[TopperT]

Just something to add......heat and accuracy is the reason I shoot five shots, take a tiny break, pick up a second rifle and then shoot another five shot group. I take is slow and watch the heat ALL THE TIIME...........I'm a bit older and retired so a range day begins with my recurve bow for 100 arrows at the 20 yard outdoor butts, ice coffee with the "boys", then drive down the hill from the trap range to the outdoor rifle and pistol range for four or five hours, and I do lunch there.....hey its the best part of a good Gun Club membership. I get in four days a week doing this, weather permitting (even winter)

Fun, friends and firearms! Can't be beat. BTW we are 1/3 of the way into our new $ 750,000 range improvement and the end result will be one of the best rifle ranges in the Northeast. I plan to do a Mosin report of the new range and the new rifles I have picked up when the range is completed in Sept.. Its a real eye-opener re: firing ranges......baffled @ 8 foot above ground, with bullet traps for 25, 100 and 200 yards.
