Recently acquired 400 .358 Dia pre lubed 105 gr. SWC bullets for 38 Special. Never loaded lead before and manuals do not show any info for this bullet. Can anyone help and provide some data for these?

I'm looking at loads for round-nosed lead cast bullet loads in Lyman's 47th manual. Interpolating between 92gr and 121gr, with Bullseye you would start about 3gr and top out about 5gr. Specifically, 92gr: 3.3 to 5.3; 121gr: 2.8 to 4.6.

Start low and watch for pressure. There are loads for others powders, too: Unique, Red Dot, HP38....

You can use any 110gr jacketed starting load. Leading will vary w/ the bullet hardness, barrel smoothness & size.

3.5 to 4+ grs titegroup.
i use 4.1 with a 124gr boolit.
just start low and bump it up till the gun functions everytime till you gget to about 4 grs.
you can use data from a heavier boolit with no problems.
