I would be more interested in making certain that the OAL is good for any and all weapons that I may want/need to use them in.
Many years-a-go, I loaded up some .357 Mags. They worked great in my S&W Model 19. BUT were too long for my S&W Model 27 and Model 28's cylinders. That could have been a bad surprise if I hadn't checked them.

I want to see what the internal ballistictisons (that's not how to spell that) say about your question.

Keep it safe,

This pistol is the only one I have in .40 S&W. That leaves me pretty free to fine tune the load to this particular pistol. Thanks for your input!
