esminbritt 16 Posted September 7, 2012 Report Share Posted September 7, 2012 My .308 is a 22" barrel. It semi-auto only. I just ordered my first csspec 20 round mag. At what rate of fire will the barrel be at risk of warping fouling easily, whatever? Quote Link to post Share on other sites
Mullet Man 2,114 Posted September 7, 2012 Report Share Posted September 7, 2012 As fast as you can pull the trigger. The firearm should be capable of ~600-650rpm (regulated). I'd say you would have to literally go thru 600rds in one minute to actually see the barrel warp. You basically bought the equivalent of a WW2 German Tiger tank in the world of rifles. Good choice! 1 Quote Link to post Share on other sites
G O B 3,516 Posted September 7, 2012 Report Share Posted September 7, 2012 That will never happen. You will have a hell of a time changing mags fast enough to heat the barrel that much. Your finger would cramp before that! Quote Link to post Share on other sites
timy 1,185 Posted September 7, 2012 Report Share Posted September 7, 2012 In my case, I fire as fast as I can afford ammo. That means a slow but sustained rate of fire that matches the nature of the beast perfectly. 1 Quote Link to post Share on other sites
VR762Shooter 838 Posted September 7, 2012 Report Share Posted September 7, 2012 It semi-auto only. They all are, unless you're out of the states and its legal to construct a new machine gun Quote Link to post Share on other sites
csspecs 1,987 Posted September 7, 2012 Report Share Posted September 7, 2012 You can blast through a few mags without to many issues... More then 80 rounds in a couple mins will make the barrel hot enough to burn you, but did not have much effect on performance once it cooled. Quote Link to post Share on other sites
Spacehog 2,218 Posted September 8, 2012 Report Share Posted September 8, 2012 How rapid can I fire my S308? As fast as you can afford the ammunition. 1 Quote Link to post Share on other sites

esminbritt 16 Posted September 8, 2012 Author Report Share Posted September 8, 2012 (edited) Iw ent into a local shop asking about a quad rail for my s308. the gut asked why. So pretended to be polite and explain to him what a fucking rail on a gun is good for. He replied "Son, that's a hunting rifle" I couldn't help but chuckle a bit. I said something like "Yeah, I do plan on hunting boar...oh, and Zombies" He laughed. I then informed him that people do surprising little hunting with AK's/saigas in Africa. They're all the rage with the kids. Sad but true. Edited September 13, 2012 by EZTundra77 Quote Link to post Share on other sites
Rhodes1968 1,638 Posted September 8, 2012 Report Share Posted September 8, 2012 A rifleman's cadence is one aimed shot every 3 seconds. In semi-auto that aint a bad rate of fire if the aim part is good. Course you could bump fire and convert money into noise. 3 Quote Link to post Share on other sites
esminbritt 16 Posted September 13, 2012 Author Report Share Posted September 13, 2012 I'm not concerned with cost, i was more referring to excessive heat that could warp the barrel. Quote Link to post Share on other sites
csspecs 1,987 Posted September 13, 2012 Report Share Posted September 13, 2012 Well when we go testing a change, we grab a case of 200 rounds and are normally at the range 90 mins or less... Its probably not good for the rifle, but I got things to do. Quote Link to post Share on other sites
timy 1,185 Posted September 14, 2012 Report Share Posted September 14, 2012 I got things to do. Like autographed 15 round magazines? Just sayin.... Quote Link to post Share on other sites
esminbritt 16 Posted September 15, 2012 Author Report Share Posted September 15, 2012 200 rounds in 90 minutes? that's only 2 rounds a minute. That seems kinda slow. Quote Link to post Share on other sites
csspecs 1,987 Posted September 15, 2012 Report Share Posted September 15, 2012 More like 2 rounds a minute and 40 minutes for the rifle barrel to cool enough to not melt the rifle case. The tempering temperatures of steels used in barrels are in the 500-700 degree area. If you get into that temp range your probably going to change the way the barrel shoots.

esminbritt 16 Posted September 15, 2012 Author Report Share Posted September 15, 2012 I love my new mag, by the way. Thank you sir. How many rounds does it take to get to 500˚ F. Say in 5 or 10 minutes. I would guess that any more that 7 rounds a minute would achieve that temp. Quote Link to post Share on other sites
VR762Shooter 838 Posted September 16, 2012 Report Share Posted September 16, 2012 I don't know many people who have taken a thermometer to their barrel after shooting. May be a while before someone can come up with an answer to that for you Quote Link to post Share on other sites
timy 1,185 Posted September 16, 2012 Report Share Posted September 16, 2012 I don't know many people who have taken a thermometer to their barrel after shooting. Rectal or oral? There is a difference. Quote Link to post Share on other sites
VR762Shooter 838 Posted September 16, 2012 Report Share Posted September 16, 2012 I don't know many people who have taken a thermometer to their barrel after shooting. Rectal or oral? There is a difference. I just shoot with a rectal. Its a comfort thing Quote Link to post Share on other sites

I would guess that any more that 7 rounds a minute would achieve that temp. I really don't know how you would get the temperature. 7 rounds a minute will probably be fairly safe, or a quick 20 rds and give it a little time to cool (I like to shoot my .22 while I wait). I have fired 360+ rounds through my 5.45x39 inside of about 3 mins, with no ill effects, other then charring the hand guard and burning the paint off the barrel. I'd suggest stopping if you smell burning paint or the hand guard feels really hot. Quote Link to post Share on other sites

There is a difference. That depends on whether you insert from the breech or muzzle. 1 Quote Link to post Share on other sites
RED333 1,025 Posted September 16, 2012 Report Share Posted September 16, 2012 I try to shoot 20 or 30 rounds in less than 10 mins, on target at range. Most times I can keep them on a 12" round steel plate at 100,200, and 300 yrds, I do miss a few times per try, not by much. Barrel gets HOT, but no problems as of yet.

VR762Shooter 838 Posted September 16, 2012 Report Share Posted September 16, 2012 I have done a few mag dumps in the x39, so I cant say from experience on the 308, but I have tried to put over 100 rounds down in under 2 minutes and barely had the Chicom barrel on my Norinco (slightly thinner than the 308 but thicker than most AKM barrels) and barely had it smoking. 308 is going to be hotter with the added powder, but I think the additional barrel thickness is going to help. You wont be bending or warping anything anytime soon. Just have fun with it, and go with the rectal thermometer like I do Quote Link to post Share on other sites
timy 1,185 Posted September 17, 2012 Report Share Posted September 17, 2012 Just have fun with it, and go with the rectal thermometer like I do I dunno. I think the oral one tastes a bit better. Quote Link to post Share on other sites

esminbritt 16 Posted September 20, 2012 Author Report Share Posted September 20, 2012 Oral or rectal is is fine. Just don't go rectal first and the switch to oral. Ever. With anything. Under any circumstances. I just remebered have a fancy digital surface thermo gun at work (like they use on racing tires). we use them for the grills, etc. I'm gonna borrow that and take it to the range next time I go. 1 Quote Link to post Share on other sites
Unknown Poster 5 Posted October 9, 2012 Report Share Posted October 9, 2012 (edited) Why punish the saiga by heating it up for no reason with sustained fire? I lube my saiga with moly and run one mag as fast as i can and still be accurate making each shot count. Just to see if i'm as good as the gun is. If there was room for a clamp on heat sink with fins that would cool the barrel like the 1927 thompson machine guns had it would cool the barrel on the saiga's more.
