Kilroy Posted December 7, 2013 Report Share Posted December 7, 2013 (edited) This might be a rookie question, please forgive me... I'm going to the range tomorrow and I am probably going to burn through several hundred rounds. In order to preserve the barrel as much as possible, how much is recommended to shoot to let it cool time? Thanks Edited December 7, 2013 by Kilroy Link to comment Share on other sites More sharing options...
TSMGguy Posted December 8, 2013 Report Share Posted December 8, 2013 (edited) These are low powered pistol rounds, after all. It's not like a full powered machine gun where barrel overheating and high temperature erosion are concerns. There won't be other than normal barrel wear, and that will be too little to actually see in a single range session. Also, the bolt remains open after firing, and cooling is rapid. There was originally so little concern about cooling that barrel cooling fins were entirely done away with on later WWII models.

Kilroy Posted December 8, 2013 Author Report Share Posted December 8, 2013 Interesting, I never thought about it that way. In fact, my 28a1 has a smooth barrel. Link to comment Share on other sites More sharing options...
mnshooter Posted December 8, 2013 Report Share Posted December 8, 2013 (edited) If you're shooting lead bullets, you will never wear out the barrel. A rental range I visited said they are still on their original 28 GI barrel, after an estimated 125,000 rounds. They shoot mostly Winchester and Federal economy ball. The counter guy also said he was not aware of the recoil spring ever being changed. They do shoot some aerosol CLP into the action every few rentals. Hoping others with personal high round counts will add their experiences. Edited December 8, 2013 by mnshooter Link to comment Share on other sites More sharing options...
Kilroy Posted December 8, 2013 Author Report Share Posted December 8, 2013 I just bought a couple thousand rounds of Remington UMC .45. It looks like it is brass jacketed? Link to comment Share on other sites More sharing options...
atc310r Posted December 8, 2013 Report Share Posted December 8, 2013 There's a reason they used 4150 steel for the barrels. Honestly, you could be in 100f degree heat on some god forsaken island in the pacific dumping one 30 round box magazine after another and still not worry about the barrel becoming so hot it wouldn't fire. I believe you would have to try and overheat the barrel, even then not sure you would be successful... On a side note, Doug Richardson's "Models" book informs that the smooth barrels may have actually dissipated heat better than the finned barrels due to more metal being present.

The1930sRust Posted December 8, 2013 Report Share Posted December 8, 2013 Make sure you spray the bbl down with light oil before you shoot. The smoke rising as it evaporates is really cool! Link to comment Share on other sites More sharing options...

mnshooter Posted December 8, 2013 Report Share Posted December 8, 2013 Grabbing a hot barrel or suppressor, much like putting your tongue in the wrong place (on a very cold day), are all part of the learning process. You become very good at remembering not do it a second time. Link to comment Share on other sites More sharing options...
TSMGguy Posted December 8, 2013 Report Share Posted December 8, 2013 Each time I take someone with no previous SMG experience to the range, I give that same "careful, the barrel gets hot" caution. Invariably, they feel the need to actually touch the barrel. Sure enough, it gets hot! Link to comment Share on other sites More sharing options...
Z3BigDaddy Posted December 9, 2013 Report Share Posted December 9, 2013 When I let someone shoot my gun I always say the same thing... "If you touch or grab the hot barrel do not drop the gun! No matter how much it hurts you BETTER hang on to it!" IJust be careful you don't touch the hot barrel by accident. Link to comment Share on other sites More sharing options...

The barrel touched his hand and in doing his "it's hot dance", he dropped the gun on the asphalt. Edited December 9, 2013 by Chromebolt Link to comment Share on other sites More sharing options...

buzz Posted December 25, 2013 Report Share Posted December 25, 2013 OP, what I do with my UZI is load the mags one at a time at the range The time interval between shooting mags due to the loading process seems to be enough to keep the gun reasonably cool One time I shot a MAC10 in 9mm without doing this, just fed mag after mag In a short time it was so hot that it was like holding a giant soldering iron, you really couldn't shoot it at that point About 600 rounds fired mag after mag in an M16 is enough to actually make the barrel turn cherry red and droop, there is a video of this on the net somewhere To summarize, I'd take it easy Link to comment Share on other sites More sharing options...

I didn't take him upon it. It's a shooter. Link to comment Share on other sites More sharing options...
