Ramming whistles

Although most say you should always press whistles as opposed to
ramming them there are instances where a rod and mallett are better
suited.  I was usind a 70/30 perc salicylate mix in 3/8 tubes.  With
little more than a tsp. of comp and proper safety gear I felt that
pressing would be too time consuming.  With some friction and impact
tests ramming was commenced.  No problems.
