AA once fired hulls

[glenns]

I have used Remington STS shotshell hulls in the past with no problems on a Mec 600 Jr loader.

I ordered some Winchester AA hulls and loaded a few recently. I am following a recipe in the Alliant Reloader's Guide.

My question is that the reloaded shell has a slight bulge (see attached image). Is this a problem? If so how do I fix it?

The newer AA hulls are softer and thinner than the older ones. You'll have to back off your crimping die a little bit to keep the hull wall from buckling. Just back it off enough to get a good crimp, but not buckle the hull.

Hope this helps.

Having gone through the same transition some 30 years ago ... Fred got it just right.

Thanks for the advice.

Is it OK to shoot the shells with a slight bulge or should I toss them?

If they will chamber, I don't think it's a problem. I shot mine with no ill effects.

Wow. It has been a number of years since I loaded 12 guage shells (all AA hulls). I am glad that I saw this. While I have several thousand of the old, hard AA hulls, I am sure that will change some day. Thanks, guys.
