    45LC Shotloads from 460 S&W Mag brass

    This is another project I just got completed. These are made from 460 S&W Mag brass trimmed down to 1.620.

    Once I put in the primer, I'm pretty much going with standard data only I reduced the charge from 7.5 published data down to 7gr and according to the tester the ones he used worked just fine. For these I'm using an Aluminum 41cal gas check as an over-powder wad, and adding 200gr of #8 shot which is a 30% increase in payload compared to the factory offerings. When I got back the cases from my tester the power ring only expanded .001 from it's original size when he got them. So what that tells me is the pressures generated from my loads are real low so the 7gr of Unique is fine.

    I used the same ole Notching die as I did with the 38/357 from the previous thread, and used a 40/10mm carbide sizer to size down the end of the case for clearance. I used a 44Mag sizer at first but it was just a bit to close in size of the forcing cone, so I went with a 40cal sizer which worked fine.

    Again: these are intended to be used 1x because the notching creates a weak spot and the brass does split. The only way around the splitting issue is to make an over-shot card and roll crimp.

    Like them! Problem is only have .45 Colt brass. Broke down and bought some#4 shot CCIs. Going to try them out on treerats.

    I wish I could find some around here that have bigger than #9 shot. #6 would be ideal for my use. A Judge or Governor would be ideal. But I don't really want either. I like using my Bisley Convertible as my squirrel gun
    You are being watched.

    Just throwing this out there, but in testing shot with a 45 Colt revolver, the best pattern I got was using 410 shells. Something about the shot cup in a revolver just worked and tightened patterns up significantly. I think the plastic acted like a buffer and kept the shot from spinning wild from the rifling.

    I cut the end off, poured out the shot, removed the cup and emptied the powder, etc. Trimmed the shell so it just would fit the cylinder shy of the throat. Used 8gr Unique and filled the shot cup up with the same shot (9 I believe). Cardboard over the shot with a dab of glue to seal. Roll crimp. I still have a few in a drawer.

    I never got around to seeing if a 410 cup would slide in a 45 or 460 case. I'm out of 410 to experiment with.

    Why crimp? Use a cardboard wad and seal it with wax. I have made cylinder length shotshells for 45 Colt with 308 brass.It will headspace on the shoulder created when you neck down the part that fits up into the throat of the chamber. You can use these over and over again.

    I had some 454 brass left over after the sale of my last 454 revolver. As made, it wouldn't chamber in the 45 Colt, but I sized about 1/2" in a 44 Spl die, then dropped in some powder, and over powder card, about 200 grains of #8 shot, then an over shot card and then sealed with glue. Perforates paper real well, just need some snakes or rats to test it out.

    Oh, this was old Freedom Arms brass and I lost one as it split when I sized the end to 44 caliber... so I annealed the remaining brass and all went smoothly.
