I joined this forum just for this post! I'm just starting with .32 H&R mag for my 432UC and have 100 round sample packs of the Missouri Hi-Tek coated 98gr WCBB and 100gr RNFP bullets. I have probably 10+ pounds of Titegroup and 2 pounds of HP-38. Been kind of struggling finding some reliable data with those powders and the coated bullets. So far I'm seeing 2.3-2.5gr HP38 (or 231)?

231 would be a good choice.

Tightgroup, and Tightwad would both be ones that would be pretty easy to work with as well. Pretty easy to get moderate velocities with a variety of powders. The hardest part about working with the .32s is handling the tiny cases. As compared to larger cartridges like a .44/45 they are darn small and your hands cramp after doing it for long periods of time! This is true of any small calibers really. I was just on the phone with a bullet supplier last week and he mentioned the same thing when loading .17 caliber rifles into his 1050 Dillon by hand.

Tried any Bullseye?

Were these the Hi-Tek coated ones I assume? I'm guessing HP38 would share the same data for these!

I believe this is where I will settle in.

Looks like a winner, that's right about where I think I wanna be as well.

Thank you @CCT125US!

I have those exact components on hand and my replacement ProChrono will arrive tomorrow.

Now...if my darn Ortho Doc will just let me off my rollator and out of this damn boot...

Thanks for breaking trail! Looks like they are shipping my 632 UC so I am sitting down with the loading bench working up some test loads. I’ve got plenty of the same components as you have so I’ll start with your load.

642 UC is in .38 Spcl, or do you have a 632UC coming?

It’s a typo. I actually have a 632 UC coming. BTW I just edited my post. Thanks
