This weekend I stopped at a gun shop to look for primers (found some) and on impulse bought some 38 caliber Acme 105 grain hi-tek coated lead FPs. However, I can find no recipes for these and hoping someone could point me in the right direction.
These will be used in a 686 with a 6" barrel, 357 mag brass, and I have Unique, W231 and True Blue on hand. My thought was to put together a light load - "mouse fart" style for paper. I've seen a couple full blown mag loads with pressures in the 40,000 range but really don't want to go there.
Any experience with these? Thanks.

While I haven't used this exact bullet, I've loaded many cast 100 grain wadcutters in .38 Special with 4.7 grains HP-38 (same as W231) for use in a pre-model 10 snubbie. These shoot to POA at 50 feet in my revolver, while heavier bullets shoot high. That should give you a starting point.

With light lead I have used Red Dot and Green Dot from 840 up to 950 fps for my X-lite loads for the kids in my 686 6" that had an average ES of 38-42 fps.

I did not crimp this bullet but did take the bell out of the case.

Ed, Sorry but what does the ES stand for. I'm pretty much a noob.

ES;

stands for the extreme spread of the shots fired in a test.

Ten is normal but some of us cheap skates go with 4-5 shots
to save bullets and get a "Ruff" estimate of what a load does....

with maybe more tests later if the load is promising..... ?
Right now I am working on the 38 special 130gr HST out of a snub nose J frame.

It can or can't help a shooter......
I shot for 40 years without a chrony and it did not hurt my shooting.

Just more data to give you gray hairs.
