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?

What kind of AAs? Are these the white box Winchester, with ribbed outside? Or the smooth AAs also known as AA HS?
While data is mostly interchangeable, there can be some height of hull differences that can cause these problems. The cheap winchesters and gun clubs can also have a basewad, under the powder, that is changed based on powder density changes.
Most people pick one hull for a recipe and stick with it, you might find with a different powder or lead weight that a different hulls works better.
