Yea but apparently the Savage ML is proofed to "129,000 Psi" I guarentee 49 grains of 5744 is not even nearing that in the Savage ML's chamber I would say 60,000 to 65,000 Psi Tops but it proabably doesnt even reach that. I emailed Toby an asked about one of the other Savage ML's that blew up on another person he mentioned in his website heres a cut and paste of from his repy in my E-mail box:

Anthony,

He said it was not from a recalled lot.

The problem with LIL GUN is that at least 50-percent
of the granules are under .015" diameter...with a
large -percentage under .010" in diameter. The
ignition system of the Savage muzzleloader has a .030"
orifice forthe fire to reach the powder.

This particular shooter surmised that some of these
"fines" had filtered through to the primer side of the
breech plug...creating much, much hotter ignition. He
came to that conclusion when he realized that the load
that did cause him the problem came from the "bottom"
of the cannister...where the really fine powder
settles.

It was more a case of the wrong powder in the wrong
gun.

Toby

I almost wonder if something like that is possible with the 5744 I doubt it but if one would push to hard when seating the bullet it could crumble some of the granules and possibly fit in the flash hole which would cause the priming to be to hot. In my Opinion still, double based nitrocellulose powders have no business in muzzle loading.
