    Let us know how the heavies in 10mm work out, please.

    I primed 1000 10MM cases this evening. I'm going to load up several different loads with a few different powders and break out the new chrono I got for Christmas..I need 1200 FPS and decent accuracy.

    I will let you know how it goes.

    I understand...life happens. Maybe I will get to some load development before then and share the results here. Assuming Montana Bullet Works starts accepting orders again.....these "shortages" are killing me.

    Tested my loads and found 3N37 and accurate 7 to be best. 3N37 gave single digit es sd numbers and great groups at 25 yds. Will retest blue dot as I forgot to arm the chrono and had no data
