Mostly true - back then those stocks with huge drop were better for pass shooting at high flyers........
That Remington sounds like a neat gun to shoot a round or two of skeet with......most likely with 2-1/2" loads
The Remington is factory choked Cyl and modified. I don't think the original intent was for high flyers. I still shoot it a good amount and take it hunting at least once a season. I've got a couple of 12ga Rem 1894s that also get shot occasionally.
