what is a CCI209 SC? I know M is for magnum, but what is SC?
It was unnecessarily manufactured in my opinion as they served no special purpose upon introduction. Not to sure that it couldn't have been a ploy to grab sporting clays shooters attention.what is a CCI209 SC? I know M is for magnum, but what is SC?
New AA is the HS not polyformed. So you better go check that data.It’s a 1-1/8 oz load. I’m assuming the newer AA Hull is the polyformed Hull. 25 gns of Universal, windjammer wad, 1200 FPS, 6,800 psi. I shoot vintage clays with an LC Smith and have been shooting a 6300 psi 1 oz load for quite some time. I’d like to give this load a try. I believe I said it was Alliant but it’s Hodgdon.
Ok good catch. So which Hull is the polyformed?
Hello Bob,From what I have read, the HS hulls ARE what they are calling "polyformed". The older Win AA hulls are what are called "compression formed". (I cannot really tell if this is true)
The Alliant reloading data makes no difference between the two, only showing Win AA hull. Vectan reloading data only shows Win AA HS hulls. Hodgden reloading site lumps compression formed and HS Winchester hulls together on the data.
What is shown in the charts is what hull they used to test and publish the PSI and velocity of the shells.
I have found no difference in loading the compression formed and the HS hulls other than the old compression formed hull is usually a little longer and the newer HS hulls length run all over the place.
If mg1polo sees this he will probably know. My 2 cents worth. Regards, Bob

Maybe I am confused or someone else is confused. Let's figure this out. Above are loads for a WAAHS and WAACF hulls. At the top is data for a Winchester Polyformed hull. Two completely different hulls and two completely different sets of data. If you are dropping 25 gr of Universal, better be sure you have the correct hull.
As labeled, the poly formed hull is used in hunting ammo.I got a bit confused n the different posts bouncing from one hull to the next.
I know what a AAHS hull is. I know what a AACF hull is. I still have a very limited supply.
What is the Polyformed hull? Not that I will ever use it, more so, I want to be sure I avoid it.
