9mm CLHP in 38/357

[billybadmedicine]

Picked up some cast 110 grain .356 HP projectiles, wanted to load them in 38 Special cases, any issue doing such?
looking at 4.5 WST, will be running in my snub nosed SP101 and a Security Six.

Assuming they actually measure .356 they will almost certainly lead your barrel. They are too small to seal the barrel and stop gas cutting.
The only chance would be if your barrel was cut a bit on the small side, but this is unlikely to happen with both revolvers.

Have you miked the boolits? If they are indeed .356, then you might get away with loading them over 3.5 grs BE and hope they obturate enough in the cylinder & forcing cone to preclude leading. Otherwise - ^^what he said...

I have loaded several hundred Lee 356-124-TC 9mm bullets in my .38 Special brass using 3.2 or 3.5 grains Bulls Eye.
Accuracy was good in my S&W but mediocre in my TC.

They were sized .356 and lubed with LLA.

BUT, Mine were cast from range scrap and measured about BNH 9. I have had very bad results with commercial "HARD CAST" .356 bullets.

I have never used anyting as small as 110 grain but If I had them and did not have a 9mm to use them in, I would certainly try them in the .38.
