Reloading 20 Ga HS Hulls

tjr61033 · September 9, 2008, 07:32 PM

For some time I have been reloading old style AA 20 ga hulls using a Mec Mark 5 equipped with a Universal charge bar, using Winchester 209 primers, Winchester WAA20 wads, with 60 pounds of seating pressure on the shot cup, 7/8 oz 71/2 lead shot (lead and powder are weighed from time to time on a scale to assure accuracy. These reloads come out as near perfect as factory loads. When using the AA HS hulls (the menu is supposed to be the same as the old style AA) after dropping the shot, the hull is too full near the open top end of the hull for proper crimping. The result is that the hull is colapsed mid way between the brass and the crimp and the crimp is convex, opened with shot showing. Is there anyone out there that can set me straight on reloading the AA HS 20 ga. hull?

FAQ: How can I get a good crimp with the new 12-gauge AA high strength hull?
Winchester has designed the new 12-gauge AA high strength hull to reload with the same reloading data as the old AA hull. However, on some reloading machines, even though the components and reloading data are the same, there may need to be a minor crimp station adjustment made. Please contact your reloading machine manufacturer if you need assistance adjusting your crimp station. Shooters have found that after making a slight adjustment to the reloading machines good quality crimps and long reloading life are consistently obtained with the new AA high strength hull.

This came from the Winchester site. You may want to query Mec about the problem with the AAHS hulls.

I've been using AAs for years but need to get some more hulls. What do the HS hulls look like?

Also saw something recently that said Remington cases were the best to reload. Know which ones they're talking about?

Thanks,
Mike

That would be the Remington STS hulls, the ones that they sell for premium target loads.
