Smith LRWF marketing verbiage touted "special boring" -
"A distinctive L.C. Smith method of choking adds 15 to 20 yards to ordinary shotgun range...specially bored to a longer, tapering choke..."
But LRWF bores are usually .730 without tapering to the choke constriction of about 3 inches.
Despite the "clean kills at 80 yds." claims, this is 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.
