I'll take it as a win. With a couple notable points.

I only fired two rounds but they told me some things, if the remainder validate the assumptions. Using H110 I got about 110 fps variation (230 gr. XTP - 1280, 1170 fps) on the two shots and noted some unburned powder in one case. This is possibly the result of standard primers for the slow powder. Snake loads (what the cases were factory primed for) surely use some type of fast powder. I bet engineers used a cooler primer than magnum loads. I'll switch to faster easier to ignite powder and drop about 100 fps.

The second thing I noted was some bullet pull in recoil. For two good whacks of recoil the third in line bullet began to pull a little. The cylinder is so long this would likely not be a problem, and that round was next to go. (*That pull might account for the other velocity being 110 fps less as previously noted.) The aluminum is obviously slicker so not really a surprise. I'll seat deeper and maybe crimp just a little, these had no crimp, just a tight case pull.

Lastly I previously mentioned how expensive Ruger Spec. moon clips were. Why didn't they make Rugers to use S&W moon clips? Other than being proprietary a-holes I have no answer. About one minute in a lathe and one could open the "clip window" in the Ruger to work with both Ruger and S&W .45 moon clips. Also I think some quick grinder work on S&W clips would allow them to work in either. I may try that just to prove it.
