Hello, I’ve got some .430 320 SSK bullets from Penn Bullets I bought years ago that I’m trying to load for the first time with H110. I need to keep the OAL to 1.6” so they will cycle in my Rosie 92. Apparently, “THE” load with these is 21.5 grains of H110. To actually get that much H110 under that bullet, I would have to seat this pretty far out, much farther than 1.6” OAL. This bullet does have crimp grooves for that and I’m guessing that’s how they loaded the 21.5 grains that’s mentioned so much and that they were using a pistol, not a lever gun. These would fit, loaded that long, in my Ruger Vaquero, and likely recoil more like my 4.75” barreled 454 Casull, but they will most likely not cycle in my 92. I did some measurements and the 100% load density with H110 loaded to OAL of 1.6” is 17.3 grains. I loaded one this way with 17.0 grains and it will cycle in my 92.
Questions:
1. Have any of you tried this bullet/powder combo in a lever gun?
2. I know reduced loads with H110 are dangerous, but I believe that has to do with available loading space, not actual grain weights. In other words, even though 17 grains is less than 21.5, because it still fills 98% load density of the remaining cartridge space once the bullets seated, this should still be a safe load, although it will be slower. The bottom picture below is a loaded round. Is this correct?
3. What’s the longest OAL that will cycle in your 92, if you have one?
4. Any other suggestions that come to mind would be great.
For what it’s worth, I also have some 250 LBTGC’s that are probably the better way to go with this gun as I can get 23.5 grains of H110 under it and still be within 90% load density with a cartridge that will cycle in my 92. I’m just playing with the 320‘s because I have 250 of them; I might as well shoot them.
