John what he says about the barrel metal melting is apparently true. He is talking microns in thickness and for less time than the flame is there. Hence throat erosion. From what I have read it is not so much on the first firing but more so on subsequent shots while barrel is hot. Takes a fair amount of powder or many shots to do this. The Bren gun had a chromed lined bore and did not suffer throat erosion like some other machine guns.

As you say, not likely to happen in a sporting situation unless you are bombing up a mob of pigs.

Agree with that.. and yes, using a high tech bore scope while at HS Precision, saw the effects of some of my rapid shooting through the years..the throat erosion was pretty bad..

One thing I took from this report was the fact I have read and been told for years that fluted barrels cool faster than a standard barrel..per this test, NOT the case..

As to stainless barrels..YES, I have lots of them.. probably close to a dozen or more.. if it's a rifle I am using a lot in the mtns, I normally go stainless..always felt they were better when in a lot of weather..rain, snow, cold, warm, etc....if it's a prairie dog gun or one I use for calling in game, no, not so much..I generally cerakote the stainless big game ones to reduce glare/shine..
