I might save up for a 4 cav of that one. Will be interested to see what you use for loads.
I pretty much use one mould for 45 ACP, an MP 4 cav brass clone of the HG 68 SWC. Great mould, great bullet, damn heavy.
Harles Dawson has a MP 6 cavity aluminum in HG 68 BB. I used his mould & made a few thousand. I shot them all in my Blackhawk. That bullet is a tack driver. I used 4 grains of Promo for about half of them & 5 grains for the other half. They would group tight as I could hold. Shot one 25 yard group under an inch. You have a great mould there Brad but heavy like you said.
5 gr of Promo is starting to get heavier than I like in my 1911. I have some loaded right now with 4.8 gr I think? I went up to 5.2 but decided it was well over my comfort zone even though they did shoot well.
Not sure what I'll use in the 1911. 5 grains worked great in the Blackhawk though.
I will say for the H&G 34 bullet I've shot several loaded with 5 grains of Bullseye in a 1911. I'm not recommending that load to anyone but I used it without trouble & sold a bunch to locals who did the same. It was probably above my comfort level also.
Longone at this point I've fired maybe 250 rounds in my Blackhawk & Kimber. I've only used one load, 4 grains of Promo & a Winchester primer. This load functioned fine in the Kimber. I had one failure to go into battery but this is a new pistol & not yet broken in.
This load in my Blackhawk is really lite, the pressure being too low to completely seal the case against the chamber.
Things being as they are here I've not fired these off the bench, only offhand. The 3 targets below were shot at 23 steps with me leaning against the bed of my pickup using the Blackhawk. As you can see the bullet/load shows promise. The lack of a defined aiming point causes the variation of elevation.
And finally here's a short video using the Blackhawk & load. The clay birds are 46 steps. The last bird I hit under leaving it with the edge to me which I failed to hit with the last 2 shots. The picture shows how they appear as they are hard to see in the video.
