I'm firmly convinced that PM's are limited purpose tubes, but I'm also sold on the belief that, within their limited purposes, they're great tubes. The en vogue thing to do around here amongst the self-proclaimed "experts" that regularly post is to bash patternmaster. That was originally because they were expensive. Then it was because those friggin experts decided that they somehow defied the laws of physics and made a gun louder, if they were ported. Then there were voluminous claims that the patterns produced by them were terrible, across the board and without qualification. Along the way, I think it just became popular to criticize the tubes and the company that makes em, and a mentality of approval-seeking bandwagon jumping became prevalent. I've used a PM tube with one of my loads since the late '90's. I only use it with that one load, but it out-patterns anything else I have by a wide margin with that load.
Either way, good on ya for doing the work and laying the results out there. What you've done is about 1,000,000 times more helpful than the usual banter 'round here.
The Patternmasters do have a bad rap with a lot of people but not just because it's based on opinion.
I had one for my Gold 10 and ran everything I could through it from slow factory loads to very fast reloads, it did well with the slow Winchester and Remington factory steel(1260 fps) loads and that was about it.
What made me return it was most of my fast steel loads were blowing apart and it was causing wad tumble with the RSI wads, which apparently has happened to others with the PM tubes. Just was not the right choice for what I wanted.
That's exactly what my findings were with them. In heavy, slow loads that employed old school, thick plastic wads, they get great patterns. With B&P & RSI wads, pretty terrible. But, for a guy that ran nothing but 1 3/8 oz loads of DryLok BB's for a decade, it was a perfect tube. My defense of patternmaster was a result of the fact that folks bashed em because they couldn't get 7/8 loads of #4's @ 1,700 to pattern through em, and therefore took a blanket stance that the tubes were inferior and that anybody that used one was both pretentious and ignorant, at the same time.
I started reloading in '07, I think. When I did, I started out with the singular intent of loading 1 3/8 oz loads of BB's in a 3" hull, because that was my go-to load, at the time. Expected to find published loads, but didn't, so I developed one, and when I did, I went with MM wads with the full expectation that it would be launched through a PM tube. It was only when I started loading 1's-4's that I reached for the other tubes on my shelf. Like I said, IMHO, PM's are definitely limited purpose tubes, but they generally perform very well when in their element.
Smell that? Smells like sumthin died in here.
