Up until the very end of last shooting season, I'd been loading STS hulls in all four gauges for the previous 8 or 9 years. I was getting them for about 1/2 market price from a friend of mine, so I could live with the drawbacks in the 28ga. I was getting anywhere from 20% to 30% failure rate loading once fired hulls (crimps that were less than acceptable, which had to be relegated to the practice bin). I could typically get 2 reloads out of a hull that were acceptable for competition, 3 was usually stretching it to the point where i had less confidence in the shells.
I no longer have a cheap supply of STS hulls, and AAHS can be had for a couple pennies more a hull over market price STS hulls. There were some growing pains switching over, and I'm still fine tuning a new load, but the results so far are very encouraging. I loaded a batch of hulls for tmrws league this evening for the 3rd time, and the shells were more than satisfactory, and I expect I should be able to get AT LEAST one more reload thats acceptable for competition, and maybe more (so I'm basically getting at least double the hull life, for only a small increase in hull cost). If I take my time and line up the crimp perfectly w/ the crimp starter, I'm getting a 100% success rate on crimps.
I'm sorry to say, but anyone that thinks the STS is a better hull has never tried the HS, or is delusional (and that is coming from a HARDCORE Remington fan, that generally doesn't care for Winchester products, and swore to never use them again after the problems they had w/ the CF hulls before the switchover).
I had assembled a large cache of AAHS 410 hulls as well, but I got to thinking about it, and I'm extremely satisfied with my current .410 load using STS hulls, and it would be crazy to mess with success, so I sold all of them, even though I believe they are most likely a better hull than the STS 410 as well. I had nothing to loose average or confidence wise with the 28, so I knew one way or the other changes were in store my 28ga shells.
