I recently traded into a S&W M&P 2.0, in 10mm. I got a box and a half of ammo with it, 180g, and it shoots to point of aim at 20 yds, groups very well, and recoil is about like my glock in .45acp, not bad. I have 400rds of ammo on the way for it, but will be reloading. In 40 I went with 165 gr and was pleased. What do you guys like to shoot in your 10mms, cast or jacketed, powders, etc, all replies appreciated.
