Einstein got us to e=mcc ... but never quite to full unification dang it !! ( g ) .
but maybe us here farmers and plumbers could get a clear understanding of just how cast bullets work ... i think our knowledge is approaching infinitely large ... and our errors are approaching zero ... all with lots of help from the CBA of course ... take a bow ...oh yeah, harry pope, and friends, who knew all this stuff a hunnert years ago ...geeesh ...
anyway, one little thing i am not sure about ... do lead bullets, unlubed and at velocities under 2000 fps ... in lets say really smooth barrels .... ACTUALLY MELT ?? from barrel friction ?
ken mollohan brought this up several times, along with some surmises ... but i am not sure i have ever seen any ... uh ... ” convincing ” double blind, etc. .... tests .. data ... to consider.
yep, we think that too small a bullet diameter lets hot gas ” melt ” the sides of the bullet and deposit that ” melted ” lead down the barrel ... that is the basis for most all our improvements recently ... either how to avoid that, ... or how to keep the deposits to a consistent ... minimum ? ... accurate ? .... level.
so do we need a lube that keeps bullets from melting ? did Mollies cow/corn meal/.. etc. also scrub out the remnants of friction melted bullets .. or did it show that bullets weren't melting from barrel friction ?
and i do remember picking up hot mj bullets immediately after firing ... was that from barrel friction ... air friction ... impact cold ( hot ) working ?
input appreciated ... we are so close to a short list of simple rules to success with cast bullets ... Sherlock Holmes mentioned ...that if we eliminate things that don't matter ...we are left with a short list ...of success with cast bullets ...
so close now ...
