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.
