Here is a story that I would go to court with and swear under oath that it is completely true.
I knew a fellow who hunted moose with a Winchester 32 Special, in the days and place where wild game was hunted year around, for meat to live on. This fellow was an exceptionally good shot and a great hunter. One winter day he went with his team of horses, hitched to a sleigh with a hay rack on, to get a load of hay from a hay stack on another quarter section of land.
He loaded his load of hay, then climbed on top to go home. in the brush off the end of the field was a moose. He knew the haystack he was at was 300 yards from the end of the field and the moose was an estimated thirty yards further, in some willows. He laid down on the hay, resting the Winchester 32 Special on the front of the hay rack. He estimated what elevation would be required with the original iron sights and carefully eased off a shot. The moose staggered and fell, dead. One shot at 330 yards.
