Way off topic, 22LR cases compared to 9mm or 45ACP

[shawnfergie]

Hey everybody. Happy late new year. Slightly off topic question.

Went to an my local in-door range a few days ago with my MP15-22, which I love, only had about 10 FTFeeds, almost no FTEs during the entire history of the gun. Puchased in Feb 2010.
Love the gun and have run about 2500 round thou it.

I also have a 9mm Sigma and 45ACP 1911. Took both handguns with me as well to the range. I was shooting the 45 and 9mm, no problem.

I then took out my 15-22 and shot, not thinking about coming directly from work and still having my shirt tucked in. A hot 22 casing went down my back and ended up burning the **** out of me before i could turn the safety and place the gun down to get the casing out of the bottom of my shirt. Shame on me and lesson learned .

Since then I've been thinking why are the 22LR casings out of the 15-22 hotter (way hotter) to the touch than the 45ACP or 9mm? I've had 22 casings from the 15-22 stick to my arm they are so hot compared to the 45 and 9mm, that I would say are hot but not all that hot.

Comparing 22s I've got a Heritage MFG 22LR and 22 Mag revolver. The "just fired" casing out of the revolver are stone cold, I imagine from the heat going into the cylinder compared to flying across the room from the 15-22.

Anyways didn't know if anybody had a reason for it. Thanks in advance.

The brass in .22 cases is very thin, therefore heats and cools very quickly. Out of an automatic, the case has just been fired a few milliseconds before, and will scorch the owie right outa yer skin. Out of a revolver or mechanical repeater, the fired case has a significant fraction of a second to cool in the chamber, and if you feel it then, seems quite cool. Hope this helps.

sorry to continue the off topicness, but which 1911 are you sporting? I have decided a 1911 will be my next gun in a couple weeks, and looking for all opinions.

The biggest thing I read out of the OP was that while he was burning, he still took the time to put the safety on and place the rifle down safely. Kudos to you. I know I probably would have forgotten about the safety if my back was on fire.

(I know it can be hard to read if there is sarcasm in posts sometimes, and I absolutely assure you there is NONE in this one.)

I've never noticed ejected .22 cases to be particularly hot - certainly not compared to my .40 S&W cases.

 

[tacticaledge]

I would maybe think that due to the smaller surface area of the.22 might not act as a heat sink to cool quicker but I know when I shoot my 9 mm those casings are usually hotter........and also were you doing a rapid fire with your 15-22 may excess barrel heat transfer to the casings......

That will make a difference.

I was at the range saturday and had one go down my sleeve. It stuck and it peeled the skin off. nasty blister has ensued. Not sure either why they are so darn hot but I had a similar experience.

 

[GeoffSFAs10]

yes they are hot. it really sucks when you have a coupel of guys raining down 22 fire on a target at the farm and if you are sitting too close they pour down your shirt. that SUCKS!! now compaired to the 30-06 brass that comes out of my garand...22 is COLD. i dunno what is up with that big gun but boy them suckers will burn your fingers even 10 minutes after sitting on the ground

I have a Rock Island GI model that I picked up in Ohio new for $400. Surely not a $1000 gun but the only trouble I've had (750 rounds) is that about every 50 rounds, one of my chip McCormick mags will lock back when rounds are still in the magazine. Good gun for the money. I was thinking about the Para GI but I saw some horrible reviews online.

Well it was busy at the range and the last thing anyone needs is to make a bad situation worse. My fault for leaving my shirt tucked in and no one else needs to have an issue because of a mistake made by me.

The rock island is my next gun choice its a very nice gun for low cheese.....

While I have been 'burned' by brass from 22 and other rounds at the range, I can tell you from personal experience- a 22lr BULLET is very hot when it winds up in you. And it seems to not cool down real quickly, either.


Don't try this trick at home kids. Uncle Paul is pretty certain you don't want to try this stunt.

Yup. All I've done to mine is change the wood grips to $10 Hogues and use some testor's model paint to put figure eight dots on my sights. Of course I spent some money on four more mags.

Every time we go my girl has one go down her shirt... She has a shell scar on one of her boobs, lol. Always the .22LR shells. 40 and 45acp no problems. It's always the 22LR that burn

Sounds like science needs to step in, who has a laser thermometer?

 

[Aceman58]

All my years on the range, all calibers if right out of the chamber and right into your neck have proved to be the same in temperature, HOT... The brass is thinner on a 22lr due to less pressure, but it can feel just as hot as a 9mm, 40 and or 45. Now the 5.56 out of the chamber right into your hand or neck, LOOK OUT, that stuff is volcano HOT.. and will burn skin on touch. Keepem on the Xring and out of your shirt...

I am looking at the SA 1911 Mil-spec...if I can find one in stock anywhere at a good price! Seems like some good reviews, and a very nice piece overall. Although, now I might have to look at the Rock Island choices...

Sounds like she needs to change the way she dresses or stay out of the way of ejecting cartridges.

The milspec is one of the best 1911s to start with. Built to spec so parts fit really well, CS from Springfield is among the top. But moreover, if you get the itch to customize your 1911 (and who doesn't at some point) it makes a wonderful basegun for about anything you can dream up. Its not gaudy with ugly roll marks, looks the 1911 part in every way. I have had many and they are great shooters. If you are able to, see if you can secure a "NM" serialed Milspec. these are milspecs that are completely assembled and fit here in the states...nothing wrong with the non-NMs, its just that the NM versions get a little more TLC.

for drool factor, check out my favorite smiths website for what can be done to the 1911 - specifically using a lot of Springfield Milspecs and GIs. Chuck has done work for me and I for him (note his company logo on his photos ) and its pure art and function and form. He is a true artisan. ROGERS PRECISION

Here is a GI and a Milspec I had worked over by some other people. They just look and fire amazingly. Good price point on the milspecs/GIs as well. Personally, if I were on the path to modification, I would go with the GI (I like the straight cocking serrations). If I were to keep it stock for some length of time, I would go with the Milspec since it has more usable sights, and a lowered ejection port

BACK on topic....yes the 45 brass is hot straight out of the gun, but not like the 22LR. What's particularly hot is when a spent casing finds it way up and over your shooting glasses that have slipped down the nose a tad and lodges next to your nose against your brow! ouch....if it can find the small opening it will....never ceases to amaze me.
