Finally got all the components to load up some slugs. Although I've been reloading for over 25 years this is my first attempt at reloading shotshells. I'm using a Lee Load All II, 12 guage. Lee 1oz slugs, Win AA hulls, WAA12 wads, 35.5 gn Herco. During the final crimp some of the cases get a crease right below the wad (only on one side) and the shell is noticably bent. I watched a video on youtube and tried putting the slug in the wad and seating them together - really messed up the nose of the slug. Started seating the wad then pushing the slug in by hand. A real PITA and every few one of the petals would fold and I'd ruin the slug, wad and sometimes the hull trying to get it out. at first I thought the crease was because I didn't seat the slug low enough (that may still be the problem) and I tried to seat it as far down as I could push it with my finger. Still every few cases I get one with the crease. Not sure if they will feed well or not. I would think when I shoot them the crease will be ironed out.any help/suggestions would be greatly appreciated.
