180 grain cast in Kimber K6

[wendyj]

My mold cast 180 grain flat nose bullet. It worked in the rifle very good and the GP 100. Now the new equation with the 2 inch Kimber. I need a load or google site for a 38 special plus P load for this little 2 inch barrel six gun. Powders on hand and not much else to choose from now are HP 38; HS6; Titegroup and Unique. I bought this for minute of bad guy at fairly close range. Going to order a 125 grain mold but already have lots of these cast and on hand. Any help please. Not asking for a load that isn’t published. Just my books don’t show it.

If you can't find reputable published data for it-- I'd just get and make a run of the heavy-ish bullets listed for it with your powders.
Getting off into uncharted waters for the 180 can have some issues with pressure and OAL.

In the 80s; after I blew up a 7.62NATO (.308Win.) Springfield M1A while trying to make it into a .30-06:
I tend not to push the envelope on that sort of thing any more.

I figure if I want close to .357Mag performance---
Rather than making my .38 into a .357Mag, its smarter, safer, and sometimes cheaper to just buy one.

I believe the K-6 is a .357 Magnum. Of course I could be wrong.........

I have used an RCBS 38-175 RN that weighed in at 181 grains with Gas Check, but that is as close as I came in a 38. I used 3.9 grains of WW-231, which is the middle of the load range published by RCBS for this bullet/powder combination. RCBS Cast Bullet Manual No.1 recommends 3.7-4.2 grains of WW-231 with this bullet. My OAL was 1.50".

HP-38 is now identical to WW-231, so you can use that data with your boolit, at least for a practice load.
