Hi guys , I require your advice, I am planning on doing bulk reloading for my 1930- 1948 S&W k frame using the Lyman 357446 Thompson SWC bullet with the AOL of 1.457 utilizing the lower crimping groove.
The revolvers are of following a 1932 M&P, a early post war commercial victory, a WW2
Victory & a 1948 C series M&P snubby.
All revolvers are safe to fire and are in very good to excellent condition.
The plan is to have a quality reloads with the same point of aim as 158 gr factory police loads.
I plan I using 4 to 4.4 grs of Unique, I am concerned if these loads may be too much for
these vintage revolvers, any suggestions would be appreciated.

Happy Holidays,
