Anyone ever heard of Rusty's Cans? I can personally attest that his designs will equal if not substantially outperform ANY commercial can. Google it, you won't find a website, but what you will find is a top contributor on another forum who provides a wealth of knowledge and experience to countless others, all of whom as I can attest will confirm that his products regularly outperform their favorite commercial cans, at probably half the cost of commercial if not less. His products are simply second to none. With all due respect, those who believe that DM components are too expensive and would rather pick up a $150 commercial can or throw together a FP contraption while disregarding quality will be lucky to have an operational can in a year, just as crappy and inaccurate as it was from day one, if it works at all. Alternatively, Rusty's Cans or one with quality DM components will cost more, but you will end up with the quietest, spot-on accurate can with minimal if not zero POI variation that is a lifetime investment (to me, at least...) Don't wish to offend anyone here, simply trying to help you find what you're seeking, just as I was; after years of experimenting, research, testing and sampling different manufacturers and varying design methods, I FINALLY found "panacea": buy the best can available from Rusty's Cans, or at least use top-quality DM or zmachineworx components. (And no, rest assured that I'm no DM or Rusty's Cans shill by any means, just an extremely satisfied customer with both!) Do what your budget will allow, but if you truly seek a quality can that'll save you 10-15+ db, not throw flyers in every direction when trying to actually hit what you're aiming at, not to mention something that'll last a lifetime, take a look...
