Need load for lee 105 in .357

[Thumbcocker]

I have searched the archives and found several loads for this cute little rascal in 9mm and .38 but not anything in .357 brass. I would like info on tightgroup as well as the other usual pistol and shotgun powders. I will not be loading hot just looking for an accurate can killer load.

Thanks

I just cast some the other day, but I'm going to use 38 brass as my goal is to load very light loads.

I used in the .357 Mag---one must use a lot of high energy powder to get a consistent spread. I settled for using .38 Spec brass with a load of 5.0 of Bullseye for 1,120 FPS MV. It is a great plinker load.

Just use 38 data since you want light loads anyway or lean to the heavey side of 38.

clays is a good powder for this application, it`s not position sensitive as some others.
i`ve used 3gr. under a 140 swc in magnum brass , any lower & you`ll smoke the cases.

I found out today that in a 38 case 1.5 grains of clays is not enough. It might work in a 3" barrel revolver but it came up 1" short from leaving the muzzle in a 4". I was prepared for that possibility. 2.5 grains seems to work quite well.

3.5 231 avg. 627 es 103
This seems counterintuitve, but a heavy roll crimp gives better consistency than does a light roll crimp or a taper crimp with these pop-gun loads. There's just not enough shank to give decent case neck tension.
