Give me a free 6mm barrel & I will make you any wager you choose that I can torch is in less than 500 with any other (suitable) powder of your choosing.
When using an overbore of any caliber, it's not the powder selection, it's how you, as the shooter, treat the barrel. Meaning: overbore cartridge + long strings of fire= toasted throat.
My statements aren't made to deride that gentlemans experience or knowledge. But to demonstrate that there may be underlying circumstances we are not aware of. For all I know he could have been shooting a CM barrel, which is well known to not be as strong as SS. Maybe it was used as an F-Class rig or varmint (prairie dogs) rig where long strings of fire were normal.
I am in no means saying Magnum is the end all-be all powder for that particular cartridge. There are many different powders that should work as well, possibly better; I do however, find it somewhat difficult to believe that a powder with nearly Identical burn rate, can be any harder on the throat of a rifle compared to similar powders. Do I know this to be fact? Heck no!
I am merely speaking from what I know & have seen elsewhere.
Magnum is a double base powder if I recall correctly, maybe the difference lies therein? I can say, I haven't seen any adverse effects, but I cannot provide an accurate round count on my rig either...
Interesting conversation! Hopefully we can get some input from guys like Kevin Thomas & Kirby Allen....
