I have been making 223 cases into 375 bullets for a few years. I simply anneal, cut the cases off then trim to the base of the neck length of a 221 Fireball (W/a Wilson trimmer) chamffer in and out a little, Then wash, tumble, wash & pickle and wash (distilled water). I made a board w/3/8" holes to hold the cases in a line and fill w/ molten PURE lead. Then lube with Imperial sizing wax, run them into a Fireball FL sizer in steps to form the ogive then chuck them into a 1/2" elec drill in a vise and finish shape the lead nose w/a mill file. They come out at about 310 grains and I use them in my 375/06 Ackley at close to 2050 FPS. They shoot about 2" at a hundred and it seems that there is not much difference in what cases are used, my guess is that the anealing? pretty well evens things out. I have shot only one deer w/them (doe @ 20 yds) and the innards were sticking out the other side when I turned her over so they work for me and are really cheap for bullets that heavy with no need for buffalo penetration. I need to find another fireball die and grind it off for one about 230 gr. for gophers!-Muddy
