To me 5000 PSI is the same regardless of what powder you use...

An SR-7625 load and a 700X load for example both producing equal pressrues are the same regardless of the pressure curve.

I shoot a damascus double. A fellow shooter insisted some powders produce less stress because the pressure is spread out over a longer portion of the barrel.

I think it's hogwash. Opinions please.

Thanks,
