Bob,
Are you saying that you are going to use 9.0gr of SR4756 in a 357mag case with a 150gr LSWC for your load?

If so, I just want to let you know something. That is real close to the load I use for the ones described in my previous post.

One caution though, I had an older M586 6" that didn't like it. The cases didn't need pushed out with a tool BUT they didn't fall out either. Work your load up from 8.0gr would be my suggestion.

Mack,
I know you have been a big opponent of the Speer #8 and it's heavy 38spl loads. Then you post loads that are considerably higher than what Hodgdon posts on their website for near this weight bullet. Can you clarify please?

Their maximum load for a 158gr LSWC is 6.5gr of SR4756 for 1214fps. I agree with the data you have posted, don't get me wrong. It just seems to be closer to the Speer #8 than the Hodgdon data. Please explain.
