.357 Magnum Data

[Beer Hunter]

I would not load 14.0 grains of Alliant 2400 in a .357 Mag!!! :O
You will end up eating white hot metal!

A quick rough and ready calculation shows over 58,000 PSI!!!

Stay safe.

I finally found my LoadAll book for the 0.357. This clearly shows 14grains Alliant way way over the top. Very glad double checked before loading.
Settled on 3.8 grains Nobel 3 pistol powder. Less than 1000ftpersec. Ideal for the range.
Thanks for positive replies.

The figures for .357 loads are generally tested in 4 inch barrel revolvers. The pressure peaks just after the cylinder forcing cone. In a 22" barrelled u/l rifle you need a slower burning powder with a more gradual acceleration of the bullet. A friend of mine insisted that 8.5gn of bullseye was fine in his Rossi 'cos the loading data said so. Two weeks later he was putting in a 1 4 1 for a new rifle.
