I would say that you paid a very good price for 50 rounds of decent SD ammo. I generally pay around thirty-six for a 50 round box of Black Hills 124 +P (bullet used is XTP).
I use 124 +P for my Glock but have switched to Black Hills 115 EXP (extra pressure) for my PM9. Great bare gelatin stats for both rounds but would really like to have seen same with denim covered gelatin.
