    I believe (wasn't there so ...) Win Mag problems were more about the chemistry of the powder than compression. Many people have long term compressed loads ( 1 member on this forum states 30 years storage ) that perform exactly as they say on the box. I have also seen numerous reports of 303 ammo and other hunting cartridges that were not compressed at all having clumping problems. As I said, I think it is wrong chemistry that causes powder to degrade and not compression.

    To say that the chemistry and physical characteristics of that powder alone was responsible for the erratic internal ballistics experienced by the 458 WM is likely not correct. I would imagine that Winchester (Olin) used that particular powder or other ball powders of that chemistry in many of their cartridges during that time and there simply isn't the history of similar erratic internal ballistics from those carts.... no matter though, every reloader makes their own choices. I simply have chosen not to compress loads and it's certainly my choice not to compress ball powder loads and in general I avoid ball powders. What anyone else does is their business.

    long range target and benchrest shooters do not use a lot of ball powders to this day due to carbon fouling in the barrel that goes ceramic.
