Still have my .50 headspacing and timing gauge from over 30 years ago
(M48/60 guy). Used to love watching the tracers corkscrewing after the
barrel rifling got worn.


I still have mine too! M113s in Nam. I used to light cigarettes
on the barrel.. and yes corkscrewing tracers are telling you its
time for a change. I thought I the .45 pistol was the oldest
weapon in the American arsenal? But I've been out of the soldier game for
35+ years :-)
