[QUOTE="44-40, post: 2876654, member: 126985"] They have barrel cooling fans, but I don't cool the barrel, just shoot it hot. Gives information about the barrel...and I'm too impatient to wait 10 minutes between shots...but it's only been in the 90°s here. And why I like the 308 win shoot them 25 rds on a hot day without stopping, heat waves of the barrel and the smell of burning steel tell ya to stop, cause ya can't make out the target, and the temperature insensitive Varget will blow primers if you haven't fired the round sitting in the hot chamber in 5 seconds. And the barrel will still be reasonablely accurate after 8000 rds. Actually tested 100 yd accuracy after every thousand rds the .1s to .3s. 3 shot groups averaged .2" after 7000 rds same exact load, for LR out to 1400yds. Just Install a new barrel and go at it again...and I have actually repurposed that firecracked 8000 rd barrel and chambering for an AR wildcat...cutting out much of the bad area, near the chamber ...some will remain...but plenty accurate for testing. Also take your 9mm pistol to the range while waiting for the barrel to cool, when ya hit 1080 rds per minute, on a hot day... So ya don't waste precious time, doing nothing. [/QUOTE]
