I've been shooting CAS for about 13 years.....here's my recipe for a light 12 ga load.

Win AA hulls
Win 209 primers
Mec # 25 bushing throws 14.1 gr of Clays ( you are correct there)
Go with 7/8 oz load, using Claybuster CBO178 wads
7 1/2 or 8 shot

If you want to stick to the 1 oz load, switch to the Downrange DRA-12, 1 oz wads. They fit the inside tapered Win AA-HS hulls better than the Claybusters. The Claybusters are a "hair" too tall and thats why you're getting the "wrinkle" towards the lower portion of the hull as its trying to smash the wad deeper to close the crimp.

I experienced the same thing when I was making some 1 oz. sporting clays loads. For all 1 oz. or 1 1/8 oz loads, go Downrange, they fit better.
