Does anyone have a source for loads using cast lead bullets with Bullseye powder in .38 Special? I found some data for jacketed bullets, but not for the cast lead. I'm trying to use 125 gn RNFP bullets. Thank you!
121 gr is the closest I can get according to Lyman's 45 edition.
Bullseye powder
starting is 2.0 gr
max is 3.8 gr
I would reduce the starting load by .1gr and the max by .2gr that should get your started.
As always, start low and work up
What he said.I wouldnt worry about reducing it at all. That lyman bullet is a 125, probably, thats just the as cast weight. Add lube to it and it is a 125gr bullet.

Richard44 said:Use just one powder for handguns, Bullseye. Works great for me and don't have a bunch of different powders. I use 2.5 gr. for revolver and 3 gr. for pistol.
Im using HP-38 and HP-38 only for 4 loads and i havent switched powders ever(well, sometimes win231 but thats the same thing). I load 102gr cast 380(3.0gr), 158gr cast 38spl (3.4gr), 125gr plated 357 mag(7.5gr) and 235ishgr cast 45acp (4.9gr). Not an optimum performer in 357 but being the cheap a$$ I am, I dont know if i'll ever buy any full metal jacket 357's to load with some 296. my 357 loads chrony at 1,400fps at the muzzle and give sub 1" groups at 15yd out of my taurus 66. Recoil is tame out of a 6" but watch out as 7.5gr can induce headaches through earmuffs and plugsI couldnt fathom using only one powder for all handgun loads. You may have an optimum powder in a few loadings, but not in all.
ot an optimum performer in 357 but being the cheap a$$ I am, I dont know if i'll ever buy any full metal jacket 357's to load with some 296.
I agree. I have probably too many powders but i like to try to find the best powder for a round I'm developing. When powders were easily available I would buy what I thought would do the best job.And there it is. I load for performance. My goal is the best ammo I can make, not the cheapest, most rounds per pound, or the fewest powders. Couldnt do it that way.
