I'm not buying the marketing, or gun writin' guy hyperbole.
Parker Bros. 1929 Catalog
"Magnum, Super, and variously named guns about which so much is now being written are not a new development in the gun makers' art. For the past twenty years Parker Brothers have made guns to handle heavy charges of powder and shot, giving good patterns at long range. Recent improvements in powder and by shell manufacturers have served to make the Parker Long Range gun even more effective, so that today the Parker built and bored to secure the full power of modern loads with which one may confidently expect to bring down game at distances a few years ago considered impossible, is up to date but not new.
Parker Long Range guns are built to guard the user against abnormal recoil. The weight of the barrels is so distributed that the gun handles the heaviest loads with comfort. The purchaser of a
Parker Long Range can rest assured that he will receive a gun, easy to handle, sufficiently heavy and properly bored to shoot the heaviest loads for the killing of wild fowl at extreme ranges."
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.
Any chance this "duck" is dead in the air?
