I would second that advice..pattern the loads you are using.
Using flushing or pointing dogs?
I had pointers when I hunted SD...also used hand loaded 1 1/4 oz.5`s., IMP. and MOD. O/U. Always patterned my loads.
I also taught myself to focus on the birds head when flushed..far fewer last birds.
That put more Birds into your vest than the pattern board.....
