I can get a limit of 15 doves with 14 410 shells
But I need to be set up at “the tanks”
Best friends Dad used to always get 10 for 10 with his Winchester Model 42 410 when we were kids, by doing that.
The limit was only 10 back then in the early 70’s.
We always accused him of waiting till the doves landed at the water’s edge, since he always snuck off to the tank by himself.
