To qualify for the Super Slam of North American Big Game®, a hunter must have registered the legal taking of all 29 of the traditionally recognized species of big game animals native to North America. For the big game hunter, there is no greater achievement and many have labored a lifetime to reach this astounding accomplishment. At one per year, it would be a 30-year quest. Some, lucky enough to get two or more, could cut that lifetime goal down a little. This gives an idea of the magnitude of the Super Slam.
The original Grand Slam Club actually began recording the achievement of taking all the recognized N.A. big game animals long ago, in the early 1970s. Grand Slam Club founder Bob Housholder was the one who began keeping up with hunters who had done so. With this history in mind, GSCO has brought this most difficult milestone to the forefront of the hunting world, and given it the prominence it deserves.
When a big game hunter chooses to register their trophies with GSCO, they are permanently recorded and preserved for future generations. Since GSCO has been keeping up with the Grand Slam of North American Wild Sheep® for well over 50 years, it is among the things GSCO does best.
