I believe you answered your own ill stated response . " Everyone Does use Which ever Dies ". Sales will bear that fact . I also prefer RCBS as they've always had MY back . Hornady, Redding nor Wilson have Never sent Me an unacceptable product ever and I use them all .
As I stated previously I have several sets of Dies as over the years I've been attempting to " Permanently Lubricate the interior of the Dies " ,thus totally eliminating need for any lube . So Needless to say I not only have More Dies than any #5 reloaders combined but also a Brand variety bar None .
I've stuck more cases for obvious reasons than any #20 reloaders combined . I also have been successful at resizing #44 ,7.62X51 LC cases without any lube ,which came from a " Generous Chambered " , aka a Worn out M60 or more than likely a now discarded M240 weapon. Cases were considerably out of spec in other words. I've lost # 0 Dies and each and everyone regardless of manufacturer ,will still load sufficiently , so as to fit gas gun chambers or bolt guns in every caliber I load for .
IF we can ever solve the PDV or magnetron sputtering inside a small diameter cylinder ,it will revolutionize the shooting sports !. Chamber throats complete Barrel bores ,lasting 100K-200K rounds and more ,dies which need NO Lube . Any interior assembly such as expander balls which must be exposed as an exterior target can be placed in a High vacuum and done via PVD . PVD is Pulsed Laser Deposition . Less than half COF of that of Teflon with Diamond like hardness !. I have them and need zero neck lube . Coating is lifetime and mere microns in thickness .
Specs and acceptance within their world. Redding dies are honed like shit and you end up with stuck cases. Had this happen with 3 different redding dies. They went in the trash. After switching to rcbs and wilson....no more stuck cases. Magic. If all dies were the same everyone would use shitty hornady or lee.
Current report a new industrial application of aluminum magnesium boride AlMgB14 (BAM) coatings to enhance the hardness of tungsten carbide ceramic (WC-Co) and high-speed steel tools. BAM films were deposited by RF magnetron sputtering of a single dense stoichiometric ceramic target onto commercial WC-Co turning inserts and R6M5 steel drill bits. High target sputtering power and sufficiently short target-to-substrate distance were found to be critical processing conditions. Very smooth (6.6 nm RMS surface roughness onto Si wafers) and hard AlMgB14 coatings enhance the hardness of WC-Co inserts and high-speed R6M5
steel by a factor of two and three, respectively. Complete coating spallation failure occurred at a scratch adhesion strength of 18 N. High work of adhesion and low friction coefficient, estimated for BAM onto drill bits, was as high as 64 J/m2 and as low as 0.07, respectively,
more than twice the surpass characteristics of N-doped diamond-like carbon (DLC) films deposited onto nitride high-speed W6Mo5Cr4V2 steel.
