I don't load what you are using, as I had terrible crimp issues with the CB 1100-12 and 8100-12 wads. I have switched to the downrange red 12A1 wad , 17.3 gr of clays or amer select, win 209 primers ( $$$, but my choice) and the new type of AA. I use a mec 9000 and no matter how I adjusted the cams it left a shot hole in the shell. Now with the DR wads they are fine. The gun clubs with the same powder loads and primers using an 8100-12 wad are better. Contents for your info only.
I load with Clay Dot also, use the down range XL1 wads, 18.5 Clay Dot, with AA, and Remington, set the first crimp die to the AA and load both the AA and Remington shells for that setting, I shoot Trap, Sporting clays with the 1 o unce loads.
If you do you work, IT shoots where you point the gun, not where you think you are pointing.
" I use a mec 9000 and no matter how I adjusted the cams it left a shot hole in the shell."
I use a 9000 also and had no problems with the 1 1/8 oz claybuster wads. When I went to the pink 1 oz wads I started having trouble. What I did was to increase the wad seating pressure to just above 40 and lowered the pre-crimp 1/2 turn, then lower the cam to max down. I also lowered the radius stage 1/2 turn down as well.
I'm loading 17.7 gr Clays, win 209, 1 oz #8, and the pink claybuster wad in an AA hull.
I load on a 9000 h use red dot 19.2 grains Spolar gold 1 oz. wad win 209 primer old and new AA hulls and have not had any issues. I only use the Spolar wads for my reloads and never have any of the issues I continually hear of on here? Cory
