HexHead... As I mentioned before here, the recoil of the 329PD in .44 Mag, (Titanium cylinder), just doesn't bother me, even with these wood grips. I don't know why not, it just doesn't. I'm not immune to the effects of magnums, they just don't cause me pain or affect my accuracy very much. Just lucky that way I guess. I use the mag rounds for hunting and the 329PD has taken many deer for me. When at the range, (being basically cheap!), I shoot .44 Specials.

Similar to semi-autos being somewhat finicky to what they are being fed, certain types of ammunition don't perform as well as others in several of the S&W revolvers. I don't think S&W would mind the attachment from Page 12 of their S&W Revolvers Manual being posted for the sake of safety:
