I've been getting some loads worked up for a turkey this spring.
I found ~30 pieces of the old Greener 14ga straight case brass on gunbroker thanks to somebody on here. I had to turn the rim dia's down a little and take some off the front to get them to seat, but only ~45 mins lathe time. I've been shooting black loads with 2-3/4Dr Fg and 1oz or 1-1/8oz of #5.
I'm getting pretty good patterns at 30yds. I haven't counted the pellets in the pattern paper yet, was just having fun making smoke. I will set up the chronograph for some more detailed data on the loads.
A no-choke mid 1870's non rebounding hammer double should fit in nicely with all the gadgeted camo turkey guns with the $80 choke tubes...
