I'm trying to find a suitable barrel for it. Yes, I do have everything needed, including a machinist. I did find a 45 Colt RH barrel, and reaming the cylinder to a tight, properly throated 45 Colt chamber would be totally suitable. I also need to look at long 44 mag bullet designs to see what I can find that would still be supported by the cylinder throats at the base while allowing the nose to engage the rifling. A 280 gr WFN sort of looks promising, but I need to consider bullet lube being slung out of the grooves as the bullet is shortened when it engages the rifling with the middle of the bullet unsupported. I'll probably play with it a little before deciding. I think a 5-1/2 in barrel 480 Ruger had some appeal as well. A Super RH cylinder would drop in, but could require retiming. I also know of at least a couple 454 std Redhawks with cylinders from SRH as well. The really intense cartridges seem to be made of special materials, or have special heat-treating. If I do it, it'll have to be special.
