Just following up here.

I reloaded 100 rounds of 357 with bullseye.

I was using 124gr Berrys plated bullets, and 6.5 Grains of bullseye with an OAL of 1.590".

The powder performed well, however the loads were pretty light. Felt more like 38 special. I will try a different powder next time and or increase the bullseye a bit. It was my first time using bullseye, so i figured starting on the low end was better.

While I was at the range, I was talking to another guy about reloading and different models etc. I was shooting my Ruger GP100, but mentioned I had a 19-3. I mentioned the loads felt light, and he commented they sounded light. So I was telling him the specs and he mentioned that I shouldn't shoot those reloads through the 19-3, that he had been reading recently as he had a 19-2, and people had mentioned that you shouldn't use any bullets less than 140 grain in a 19-x as they apparently damage the forcing cone. I was surprised to hear this. Wondering if anyone knows about or has heard anything like this?
