As I most of you here know I have finally tried loading for shotguns. I loaded up a dozen FG black powder 2 7/8” 10 gauge loads to try in my Damascus 10 gauge SxS a few weeks ago and I’m hooked! I tried a square load of 116 grains of FG and 1 5/8oz of #6’s. I also tried a 100 grains of FG advised my another member here which turned out to be a pretty darn good load. I put 40 hits in the kill zone on a turkey target at 25 yards with the left barrel. I used RST spent hulls and I glued in the overshot card. I just bought a quad pin roll crimper. So now, instead of gluing in the shot cards I am changing over to roll crimping them.
How much, if any, pressure increase will I gain going from gluing in an overshot card to a roll crimp? Will my pattern stay the same,or close, from changing over to a roll crimp vs a glued in shot card with the exact same load?
Also, I forgot to resize two hulls that were shot in my Gold. I already had packed 2 hulls with 100 grain FG load and a 1/4” nitro wad over it before I remembered to see if they would easily chamber in my SxS. They chambered with a little pressure so I resized the brass with the powder and nitro card already installed(trust me, I won’t be doing it again like this). Both the loads were GENTLY tapped out of the MEC screw in sizer die with a chrome rod that comes with the lee loader 2 7/8” kit. They now chamber easy. The question is I could here powder crunch when I seated the nitro wad over the FG load pretty good. Im sure tapping it probably broke up some of the larger granules as well? So is it possible to use to much pressure to seat a nitro wad over black powder?..and if so “how hard is to hard” when compressing black powder in shotgun hulls? My goal is to stay under 7000 pressures. The only load data I have seen a pressure listing using 1 5/8oz of shot with black powder charge in a 10 gauge 2 7/8” hull was using 130 grains of FFFG and a 1 5/8oz load. It was listed at 6700 pressure. So I would assume I am way under 7000 pressure even if I crunched powder?
