I shoot 7.8gr of HS-6 with 125gr XTP and get little under 1100fps. Thats not bad and good as it gets.

But out of the same Model 13 357 mag, I shoot 10.5gr of HS-6 in 357mag cases and get little under 1500fps. And thats mind. I also load 21gr of H110 and know I am getting upwards of 1800fps.

There really is no comparison when handloading.
