need recipie for 9mm 102gr cast bullet

[hangfire]

Hi,

Lee makes a bullet casting mold for a 102 grain swc that is supposed to be fine for either 380 or 9mm. I want to do some loading with this round in 9mm, and planned on using bullseye (my powder of choice). Anyway, there isnt a suggested "recipie" for this load in my lee reloading manual, and a message direct to alliant powders resulted in them suggesting an absolutely anemic load (2.5 grains bullseye) in 380! The lee manual reccommends 3.2 grains for 980 fps when using this bullet in .380.

Anyway, looking for advice on what to load this round with. I also have some red dot, and I think some unique, so I guess I could use one of those instead of bullseye, but bullseye is generally my powder of choice.

Hi HF
Just happened to have Speer's #10 manual next to me when I read your post. On page 353 for 9X19mm data their 100 grain jacketed hollowpoint is pushed with 6.0 grains of Bullseye to get 1330 fps. Starting load is 5.4 grains at 1220 fps. With your cast bullet I'd expect you to get maybe 10% more velocity over a jacketed, so maybe in the range of 1470 fps max. I'll check my Lyman manual for some additional loads when I get home tonight.
Good luck,
Michael

OK, on page 383 of the Lyman manual #47 there is data for bullet 356632, which is 100grains when cast in #2 alloy and loaded to an OAL of .976". The starting load with bullseye is 3.3 grains for 1157 fps and a max load of 4.4 grains for 1395 fps. That looks like significantly less bullseye than in the Speer manual. Hope that information works for you.

appreciate the response. How fast is still ok with cast lead bullets before you start seriously leading the barrel? I'm also considering using these with my highpoint 9mm carbine, so as I understand it, they will travel 100 to 200 fps faster then out of a pistol

I routinely make Lyman #2 alloy (90/5/5% lead/tin/antimony) for everything I shoot. I load a 150 grain .358 SWC in my .357Mag that I shoot in my Marlin rifle at about 1800fps. The little leading that occurs usually cleans out with nothing more than a tight cotton patch. As long is it's cast in hard alloy and not soft-swaged lead bullets, I don't think leading is a real issue up until you're past 2000fps.

Leading problems have been reported at as low as 1,000 fps using pure lead. #2 or wheel weights with a gas check can get you some higher velocities. Barrel smoothness effects this too.
