ok, so i've accumulated several barrels over the years, stock bbls for the ion, and impulse, progressives, teardrops, all americans, heck, somewhere i've still got a big daddy. i've been told several times that all SP barrels are .689, regardless of style. does anyone here know for sure? preferably with some sort of documentation (confidential smart parts inter-office memorandum?;) ).

if they are truly the same, then i could stand to sell some and be none the worse. thanks for reading, dav
