I am looking at reloading for my 12ga 870
I'm using a MEC 600jr and have colected many Winchester hulls.
They say; " Winchester AA. 2 3/4 1 1/8 #7 1/2 super sport" in black letters are a smooth sided graphite grey color with a low brass.
I can't find any info on these cases in my Lymann shot shell reloading handbook.
Can anyone tell me what type they are?
Winchester HS? Compression formed? Polyformed? Something else?

Winchester AAs are a very common hull. The require a taper wad something like a Claybuster 12SO, 18 grains of 700x, or promo and 1 oz of lead.

Look in the Hodson reloading manual.
 
Winchester "AA" hulls come in red and grey.
Based of your description and no picture to compare... Lyman 5th edition book, page 34 I would go with data for the Winchester HS plastic with plastic basewad and Winchester compression formed plastic.
They both use the same data.

What reloading components do you have on hand?
 
Yep - the gold standard. There was also black ones available way back in the day.... I just went thru my ancient box of trap hulls and all my old AA's were red and black... surprisingly, also found an old stash of 150-200ish of old once fired RXP green cases and Peters Blue Magic cases... anyone remember those??

Christ I know I am old when?? Remember Blue magic and rxp I am still reloading them.;);) First bin I opened had some blue magic on top . If I dug probally have a couple 1000 of each and at least 500 of the old black TRAP AA's . In fact still have some of the black unfired in their original boxes. Old to me is win red 20 ga. :)

Ok thanks. Because the manuel has no referance to AA hulls or any mention of Winchester grey hulls.
I thought they might be the same as the red ones but the book seems very presistant that changing one component for another is very dangerous.....seems that even a primer swap could change my mild trap load into a bomb shell......

As for components, I have;

Grey Win AA hulls (garbage bag full + most of their original boxes
Gold Remington/ Peters hulls a grocery bag full
Silver Win AA hulls a grocery bag full
Federal plastic gold metal hulls grocery bag full
Remmington STS 3 boxes
Remington hi brass 3" hypersteel 2 boxes
Winchester hi brass 3" hex shot 2 boxes
Clay buster W12F114 wads

25lbs of # 7 1/2 hard lead shot

700X 14oz (not a full pound these days?!)

Win 209 primers

It was my idea to make some 1 1/4oz field loads and then add a card to the wad and load some 1 1/8oz trap loads....but 700X doesn't show up under 1 1/4oz load listing and adding a spacer to the coloumb could aparently do a lot of damage to things including me......
Time for a rethink acording to Lyman

If your manual doesn't reference AA hulls then throw it away! The AA hulls are arguably the most well known hulls on the planet.

It doesn't say anything about AA hulls persay. It lists three main Winchester hulls and any one of them could have AA printed on them at the factory, atleast that's my guess.

I have been told that the older AA's were compression formed tappered wall cases but the newer ones are the HS hulls with seporate base wads. I'm told that the new ones don't hold up as well as the older ones, 3 reloads can be done.

Now that I know colour of the hull means nothing in this paticular case I'm pretty shure I know what they are.

Not sure who told you the newer ones don't hold up. In the small gauges they are lasting almost double and 12ga about the same. Three out of any of the winchester AA's is a joke at least for the pressures I use. Six min for most and many guys reload them 10-12 times.
As long as not split and they will still hold a crimp they are fine for me and I have had years reloading 25,000 AA's in all gauges and no issues.
 
On the wads don't waste your time playing with the 1 1/4 oz for target loads. For the sake of 12 bucks pick up the bag of 500 1oz claybuster / winchester clones.
If you are not sure what hull you have post a pick and the boys here will ID it for you. If it is an odd ball I have a cut copy of just about every plastic hull known to man in a big container and will be able to match it with any recipe pic shows about 40% of them
