I shoot Berry's 220gr flatpoints for target shooting with my S&W M29 6.5". My usual load is 9gr. of W231. Looking at this data from Winchester (maximum loads in both cases:
220 GR. BERB FP GRS. 9.4 VEL.(FT/S) 1104 PRESS. 20,700 PSI
225 GR. SPR JHP GRS. 11.0 VEL.(FT/S) 1344 PRESS. 38,200 CUP
I wonder what would happen if I went to 10gr. of 231.
(Yes, I know there are other powders that are more suitable for the .44Mag, but I have a lot of 231 on hand.)
