Ball powders in 308 with 168g match bullet?

[Infrequent Shooter]

Just as a cautionary note,
I had a really old can of Win 748 that had been sealed and unused but was about 30+ years old and when I used a fairly conservative dose behind a 168gr Hornady A-Max; the first {and only} shot went off with gas blowing back through the action and the primer falling out when the case was extracted...!!!
A week later someone else at the range had the same experience, also from some very old 748.

I suspect that like some wet looking dynamite I saw many years ago in an old gold mine I was foolish enough to explore,!!! the nitroglycerin had sweated out and now making the whole lot very unstable.
I quietly backed out of the mine that collapsed about a year later when the shoring timber failed and think myself lucky that all had not ended in disaster {Fatal} for me...
The same with the old Win 748... It got tipped out on the garden and I felt lucky that I didn't have a bolt through the face.

!! the importance of the bolt cutout in the stock, saves us again and again.

Love powerpro 2000mr in my 26” 308 with 168 berger. Also with 180 berger and 208 bergers. Excellent velocity and accuracy for me
