Ok, here's this weekend's project to make .40 caliber bullets with CH 101 dies. *I used the same 110 grain lead core I used for my .357 bullets. *First I heated a batch of 9mm cases in my empty Lyman lead pot set at 700 degrees F for 2 hours. *That worked nicely, without any of the scale I get on the kitchen stove. *Because the core is so short for the 9mm case (or the case is too long), core seating just resulted in damaged jackets. *It was straightforward though to just drop in a core and send it up into the swage die.

Look carefully at the mouths of the bullets in the middle group and the far right group. *For the far right group I left the jacket in place to form an open point that extends about 50 thousandths past the end of the core. *In the center group I folded the end of the jacket over the outer lip of the hollowpoint to make a jacketed hollowpoint that extends right to the mouth of the hollowpoint with no exposed lead. *
The nominal weights of both bullets is 172.5 grains with a final diameter of 0.3995". *The hollowpoint measures 675 thousandths long while the open point is 715 thousands. *I've shot neither of them yet, but I would guess the folded-nose hollowpoint might feed better and also stabilize faster than the longer open point.
