I wanted to try some 3/4 oz loads using 8 1/2 shot, Win AA hulls with a CB0175 wad, Win 209 primer and about 15 gr Extra-lite powder. Shells were loaded on a Spolar loader. I was surprised to see the crimps were extremely dished. I shot 50 today and they shot well and broke targets. They just didn't look too good. Any thoughts on why the dished crimps? I've loaded 7/8 oz that came out perfect with CB0178 wad.
