To date, I have only shot some of his 10mm loads in 135gr nosler, 155 and 165gr gold dot and some of his 125gr 357 sig gold dots. Have been checking all the brass, No overpressure signs on any so far. I will say this, His latest 357 sig load 125gr gold dot. rated at 1475fps feels very stout. Shooting that load from a M&P 357 sig 5 inch Storm lake bbl. Wish I had a chronograph. if these videos are accurate it looks like he is underrating the velocity.
