Spring 2013 "Double Gun Journal" Volume 24, Issue 1, p. 137
Pattern testing by David Williamson with .042" choke 32" LRWF at a measured 80 yards using 3 inch Winchester (plastic) hull with 38.35 grains of Blue Dot, Winchester 209 primer, Winchester AASL wad, and 1 3/8 ounces of #5 nickel plated shot.
The average number of pellets was 246 and measured weight 1.353 ounce. Number of pellets in duck for 3 shots: 5,6 & 6.
Pattern % in 30" circle: 5.3 = 13 pellets, 8.1 = 20 pellets & 8.5 = 21 pellets.
Maybe a Davis Hy-Power would do better
The shell headstamp is "Western Record" NO idea about the "parchment paper capsule that extends beyond the chamber into the bore of the gun."!?!?
