Can you use magnum small pistol primers when loading .40S&W?
No problem. I've done it and only seen an increase of 20-30 fps over the chrony. And with light loads they can improve ignition.

ETA Though I and others do it I should probably tell you to work your loads up.
Awesome, Thank you. I scored some mags and planned on using them in my .357 but now will use in both.
Yeap, a have a nice little lite load for my 38SPC snubby for plinking. That's were I use my magnum small pistol primers. I save my regular primers for my full house loads.
