Jim,
Great information. Way more than I expected. I wish there was good smokeless data for the MagTechs.

I have an unopened can of SR4756 and with only 10 RMC 16 cases it will go a long way. I have a Manufrance whose right barrel is rifled and when I bought it I expected it was a ball and shot gun. It appears, however, that the rifling was meant for control of the shot pattern. Anyway, half of the RMC's are loaded with paper jacketed 435 gr conicals and the other half with round balls. I have not tested these and with what I now know I will probably disassembly them for shotshells.

Thanks for taking the time to post the data. Incidentally, the pheasant population in western Nebraska is pretty amazing-like when I was a kid there. Just across the border for you. The CRP land we were hunting was positively devilish and we had to keep Pepe booted the entire time. Combination of head high sunflowers, thistles, impenetrable tumbleweeds and other things that clinged, scratched and poked.

You have a beautiful French Brittany.
Dennis
