Admittedly, I have given you Bra guys crap over acting like it's a magic pill. I even joked once about y'all sleeping at nite. I do however want to be crystal clear...I don't think it's a ploy for y'all to line your pockets. Whether it's a dasher/brx/bra you make the same spinning barrels up.
You've obviously done testing to convince yourselves it's better. I've not tried one but I'm not convinced...maybe I will or maybe I won't. Point is, it's not going to turn an average weekend warrior into a winning machine. I've figured out a long time ago, there is no shortcuts in this game...nothing beats throwing bullets down range.
I also will say I've never really understood the whole "it's easier to form brass" because I've never had an issue with the false shoulder method of forming either brx or dasher. I do get some short ones sometimes but I don't get many.
Bottom line, I think it's cool you've shared your experience and I do appreciate it regardless if I ever build or spin a dasher killer
