Put some of this in context. All of the test barrels we made and sent to ammunition and bullet makers all came back with no negatives.The bigger question is the 400MOD just
marketing hype or is it to hard for magnums using high temp powders. Can I cook one using 570 in a standard 300 RUM?

The very first one we made went to an ammunition/bullet maker and the caliber was 6.5CM. Normally on p&v (pressure and velocity) test barrels which also can be used for accuracy have an average barrel life of only 1700 rounds. Give or take a few. That barrel went 3400+ before they seen any issues with it. They ran another +100 rounds thru it to confirm what they were seeing, and the barrel was considered toast and it was pulled from service.
We have a different ammo/bullet maker that every barrel they order in a rifle caliber they are buying the BB material and paying for it. Not just one or two. They will order 10 at a time in calibers ranging from 223 to 308w, 6.5CM or 300wm etc... not a single complaint or phone call back with a problem. Now all of their pistol caliber test barrels they are buying standard SS material barrels. Why... pistol barrel in like 45acp could go 90k rounds before its junk. So, in the case of the pistol barrels, they can't justify the cost for the BB material.
