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,

You well want to stay in the standard 38spl range 15 to 16 thousand PSI. and away from +P and +P+ data for sure 4 to 4.4 should be with I the standard load data range.
