Have an early '20s I frame revolver with 3 1/4" bbl. Casting 90-100 grn SWCs for it. Prob 90-100 RNs, and maybe WCs also in the future. What load data for those bullets are you using? Nothing but a fun gun to kill paper with. Anything that is paper accurate and won't beat the old gun up, but will let me enjoy shooting it. Thanx
PS: I have a lot of the manuals, and Load Data subscription. Just looking for personal loads that you have found to work well.

I use 2.0 grains of 231 with the 90 & 100 gr bullets. Nice and soft shooting. Larry

Mine is a modified I frame with the coil spring. It sees a lot of 2.5 gr Red Dot with the Lee 90 swc. No need for hard bullets with these guns, cast soft and shoot slow and the grins will be there.

I’m using 2.0 grains of Titegroup with a 95 grain SWC with good results. Very mild.

My favorite load for my '20s vintage Regulation Police 32 (6" barrel) has long been 2.2-2.5 gr Bullseye behind a 95 gr swaged SWC. I think even the higher end load is still safe for about any swing-out, solid frame S&W, but YMMV.

I do 2.1 grains HP-38/231 with a 98 grain wadcutter. That reminds me, I need to chronograph that.
