I use to use them and still will but I stumbled into some 16 grain and was quite impressed so got some rws superfields and was impressed. Then I got some jsb of similar weight and was impressed.
I don't mind loopy trajectories mate. I will work with mother nature before I'll ever try and resist it! ?
I use to use 22 bizzy mags in sub 12.
Under close woodies they were good.
My fave weight for sub 12 is 16gn these days. They seem really stable to good distances.
