Interesting Recoil Comparisons and charts

    Found this stuff somewhere on the net a long time ago.

    According to the Shotgun Recoil Table the recoil energy of a 1 ounce target load at 1180 fps in a typical 7.5 pound gun is 17.3 ft. lbs., about like the recoil of a .270 rifle. The typical promotional shell with 1 ounce of shot at 1290 fps in the same shotgun hits back with around 20.8 ft. lbs. of recoil energy, about like an average .30-06 rifle. These loads deliver about as much recoil as most shooters can stand on a continuing basis.

    A typical high-brass load with 1 1/4 ounces of shot at a MV of 1330 fps fired in a 7.5 pound shotgun is much worse. It belts the shooter with 36.4 ft. lbs. of recoil. This is roughly equivalent to the kick of a .300 Ultra Mag. rifle. Average hunters should strictly limit the number of such loads they fire to avoid developing a flinch.

    12 gauge Magnum shells are even worse. A 2 3/4 inch Magnum shell throwing 1 1/2 ounces of shot at 1260 fps from a 7.5 pound shotgun belts the shooter with 45.9 ft. lbs. of recoil, somewhat more than the recoil of a typical .375 H&H Magnum rifle shooting 300 grain factory loads! And the 3 inch Magnum 12 gauge shell firing 1 7/8 ounces of shot at a MV of 1210 fps in that same 7.5 pound shotgun slams the shooter with over 60 ft. lbs. of recoil energy. This is equivalent to the recoil of a .378 Weatherby Magnum rifle, and exceeds the recoil of a typical .458 Winchester Magnum rifle. This is literally recoil in the elephant gun class, and most shooters would be well advised to avoid such loads.

    Good scoop. Us trap gunners have to stand one or one and an eigth low brass all day (to 300 birds.) We know when those days are done, I can tell you. Typical v=1200 to 1300 depending a bit. I recently had the chance to shoot some 7/8 ounce over Unique. Very soft, running close to 1250. Nice loads worked up by a guy at the range. If I ever get into reloading, I'm going to try duplicating it.

    I've shot a lot of sporting clays myself, so I know the feeling. I buy bunches of 1 ounce loads when I find'em, 7.5 so I can use them for clays or dove season. That one eigth ounce really does make a difference after a hundred rounds or so. I'd like to go even lighter, but then ya gotta buy the premium stuff. My double is pretty heavy so that takes up a lot of the recoil over time.
