Looking into reloading 2-3/4 Winchester AA hulls with 1-1/8 shot. What do you all think of WST and Blue Dot powders? Any other suggestions on what works best for you would be appreciated. Whats your favorite receipe? Thanks in advance.

regardless of powder, a "light" load requires a light charge of shot.  Try 7/8 or even 3/4 oz loads.  You'll notice the difference in recoil, but not on the targets.

All of the powder makers have on-line loading data.  Just go to their websites and take a look.  With fast burning powders (i.e., shotgun and pistol) being very scarce right now you sometimes have to make do with what you have. 

You have to look at the whole system. But as Stu kettle says, a lighter shot load has the greatest effect in lowering recoil.

The RULE in loading shot shells with smokeless is NEVER VARY FROM A PUBLISHED RECIPE. So look through the reloading data bases for what you want.

Having said that, here is a formula that I have used in trap shooting for years, and carried over to CAS until I went to the Darkside;
-  Win A-A hulls (Old style- 'cause I have a bunch!)    ( R-P RST, Nitro27 or Gunclub are also very durable, and are close to the same capacity.)
- 209 primers of most sorts; - But see the rule in CAPS. above.
- 16 - 17 grains of Red Dot or better still Green Dot.
- AA or Claybuster pink wads for 1 to 1 1/16 oz loads, or grey wads for 7/8 oz.

There are many similar formulas in the data bases, and especially a wide variety of wads. You will find that your game, or clays, or knockdowns will not miss all that expensive shot you will be saving.
