As we all know, there were a great variety of rifles used on the frontier through time. A lot of the early fur trappers used plain ol' PA made rifles, as from Lancaster and other points east. The Hawken boys set up pretty early in the "mountain man " period and we know some of the lads toted their rifles--especially in the later years. The Hawken rifles were [are] great hunting guns and their use as such lasted into the 1870s at least. And they were not all big bores. A former neighbor of mine had his great grandaddy's Sam Hawken rilfe that he took to Arizona when he pioneered out there. It was a ~.32 +/-! It was the first real Hawken I ever held [this was ca 1966]. I don't remember what date he took the rifle out there, but the style was typical of the percussion rifles they made, just small bore. Obviously he was not a big game hunter...
