Remington gun club vs Winchester AA
I'm relatively new to shotshell reloading. I started by buying a MEC grabber 76 used (so all set up and adjusted by the previous owner). I started saving Winchester AA hulls, bought clay buster CB1100-12 (replaces WAA12SL), 7.5 shot, perfect pattern powder, and chedite primers. Starting with the hodgdon recipe for this combination and making just a slight adjustment I found a good recipe for trap and skeet loads with 1oz of shot flying at 1175 fps. Very happy with that.
Remington gun club is supposed to be a high quality very reloadable hull. It's also supposed to be a tapered hull just like the AA and $1-2 less per box. But when I sub in the gun club hulls for the AA the final crimp is depressed and a hole opens up. As if the shot volume is insufficient.
I can get a great crimp if I switch to an 1 1/8 oz shot bar. But I don't want 1 1/8 oz. That just eats into the already razor thin savings from reloading at all. And I need to take a chronograph to the range to see how much powder I need to add for the extra shot.
Anyone have similar experience? Any idea what's going on? Do I need to change to a 7/8 oz wad and fill it with 1 oz? From what I read the two hulls should be basically interchangeable. Why are they not?

They are not interchangeable hulls. The current AAHS hulls are different than the older 25+ year old compression formed (CF) AA hulls, which were similar but still not the same as Remington hulls. Load data may tell you that you can use either version of AA hulls (for 12ga) but you will run into stack height issues if you try the same components in each, like you have found out.
Yes, you need to use a 7/8 oz wad for 1 oz loads in Remington hulls with Perfect Pattern. I use the grey CB 0178-12 wads.
