Many would argue that point, me included especially in the 12 gauge. If you want to load one oz loads in a WWAAHS 12 hull and throw powder with a mec #30 bushing or larger, you better use a 1 1/8 oz wad to get a correct crimp. There just is not enough room inside.Not sure what phezbuster means by the difference between cf and hs AA's. Internal capacity is the same, so same data applies. I don't even sort mine
This is caused by too much wad compression when crimping, caused by the reduced interior volume. If you use a 7/8 wad for 3/4 oz in the 20 you should not have any problemFor 20-ga? There is not even a close comparison; STS Premier is the best. The reason why you find so many of the HS around the club is that people throw them away! The AAHS often will come out looking great, box em up, three days later they have gotten pregnant to a point where they are dropping shot lose in your pouch.
You will regret it if you switch to STS in 28 gauge.I load 28 gauge with the AAHS 3/4 oz and they seem fine. I think I will go with the STS. I shoot with some guys that load them in 12 and they really like them. They say they get lots of loads out of them.
Actually, 296, H110, and 300 MP are just as bad or maybe worse for leaking under the Universal Charge Bar. The tolerance gap between the valve and the bar is often wider than the individual grains of powder and they fall through. I actually had Multi-Scale replace a bar after I sent them pictures and explained the problem. The replacement bar leaked even worse!If you use a Universal charge bar with a fine powder, you should expect to see powder falling out from the under side of that bar. It slips between the underside of the adjustable slider and the measure assembly. The worst is Titewad in the 12 Gauge.
