I switched my CVA to 209 primers, because I hade a couple misfires with #11`s.
Though I admit the misfires were not fresh loads, they were only a couple of
days old and well taken care of (not been in rain or major temp change).
I dont change my load after each hunt, I use the same load for several days hunting,
provided the weather was good etc.
I havent noticed any change in my groups but if I did I would accept a small loss
of accuracy just to know that baby is gonna go boom when I squeeze the trigger.[&:]
