I've cast and shot about 4k through my M&P40 this past year. My bullet is the 401-175-TC.


The Lee 6 cavity mold cranks out the bullets in a hurry. This is the output of a little over an hours worth of casting.


Be sure to slug your barrel to see if you need to size your bullets. My bullets drop out at 0.4015-0.403 depending on the alloy. I tumble lube them, size them through the 0.401" Lee sizer and do a very light tumble lube again using Recluse's 45/45/10 formula

When seated to 1.135" and using Unique, I average 950 fps with 5.0g, 1020 with 5.5g and 1080 with 6.0g out of the 4.25" barrel. The majority of loads I shoot is at 5.0g because I am usually just punching paper while practicing trigger control and trying to keep my shots in the bullseye. 5.0g gives adequate pressure to seal the case, prevent gas blowback and keep the muzzle clean.

Hope that helps and Happy New Year too.
