I have some Hornady 170 gr Interlock bullets that I would like to reload. I also have Hodgdon H110 and Lil-gun powders that I would like to use. Can anyone here direct me to information on a starting load with both these powders? Thank you in advance for your help with this matter.

I have Hornady manuals going back to 1982, I don't see any evidence that Hornady made a 170 grain,
.357 bullet. According to my resources, Sierra and Speer make a 170 grain.

They are .355" made for the 350.

I'd start at about 24.0 H110
Hodgdon has data online.
I got a stiff bolt lift at 26.0.

I had a load worked up for my Ruger last year. Got a Savage recently and the loads were blowing primers and also losing chunks of brass at the neck. That was with Maker 150 TREX and Lil' Gun. Going to back off a grain or so and see if that works
