Default 320gr. .44 Special standard pressure?

I picked up some Cast Performance 320gr. bullets from a buddy- only about 36 of them, and I want to know if anyone can suggest a standard pressure load to try on them, in a Ruger blackhawk and my 2nd model HE's.

I have never loaded anything this heavy in the Special before, but wouldn't mind trying this few to see how they work, but more than anything, how they look. I have no idea how they will shoot, but I think they will certainly fill the cylinder completely and make some great photos- I'm goin' to keep six just for this purpose.

Suggestions appreciated.

I went and checked one of my sources that always has good info on stuff like this, and the only thing that comes close is a Dry Crek 307 grains cast swc over 15.5 grains of H-110 for 1050 fps. That is a 25,000 PSI or slightly under load and well above the pressures you stated you were looking to work at.

That load would be completely safe in a Ruger Blackhawk or S&W 24-3, but not a 2nd model HE. If you are going to stay at normal SAAMI spec pressures of 15,500 PSI or less, I believe that you may run the risk of sticking a bullet in the bore. That is a long bullet, with a relatively long bearing surface, and at that low of pressure they just might not clear the barrel, and they wil certainly be going very slow. Based on all the data I have on hand for the .44 special, I would guess 600 fps or below which just isn't enough to reliably make them exit IMO.

To add to your problems, I expect that bullet is going to have to be seated very deeply in the case. I really wouldn’t know where to start.

Sometimes freelancing too far from existing data points can dicey. Don

Ok. I'll just keep them for photo ops...unless I get another .44 Magnum.

Andy,

Handloads.com lists some Special loads with a 300 grain bullet. Depending on your courage, you might work something from there. Keep us informed. You see, I have a bunch of those bullets too as well as a 696 and all my 44 magnums have moved out. If you survive, I'll give it a try, although I must add that recoil was brutal with those bullets in a Superblackhawk.

As my friend Gun 4 Fun has posted, your stated pressure limit of 15,500 is pretty low for a bullet that large. It would likely stick in the barrel.
The 307-grain load is well-tried, but is at 25,000 psi or below.
It is one of Brian Pearce's loads and you can read about it in a proper issue of HANDLOADER magazine. It uses Federal 155 Magnum primers in order to get that powder lit. Standard primers will not do.
So, if you want 15,500 psi or below, I'm of no help. But the 307-grain load is a good one, with the proper gun.
