I'll beg to differ there MG. My manual is full of Universal loads for the SW and a few taper hulls loads too. They are somewhat higher charges than Titewad in grains used. The only thing about Titewad I don't like in 9/8 loads is ya can't load much past 1200 fps without running into pressure problems. Titewad may be one of the best powders for 9/8 loads, but the OP said he was using RIO hulls.
I respect any reloaders choice of components. I have reloaded shotshells and metallic for almost 45 years. Back in the day, the only hulls (once fired) one could readily find was the target hulls, mostly AA and Remingtons. We didn't have the many choices we have today. We typically paid 8 cents apiece back then. Today, because of more shooting, the cost has come down, but it still ain't free, like all the SW hulls I use. I have also found I can load just as quality a shell in any SW (eurotrash to you) as those in the club that insist on loading only the coveted Premiers or Nitros. I don't load any hull but once, and it's in my trash, I don't put them in the bins. It ain't as much the shell as it is the dude behind the trigger. I shoot as well as most at the club and better than many, and I do it with an infinite supply of free hulls.
