This is a very strange discussion.  I take it you are all talking about a full stock Hawken.  I hope the ramrod groove and hole is 3/8" diameter.  I cannot understand Bob Roller's comment about tapering the ramrod end to avoid the front bar of the set triggers:  if your hole interferes with your triggers, A) the hole is too long, B) the architecture is crazy.  Now, the ramrod groove should be no deeper than 1/8", revealing 1/4" of the rod.  This is the traditional technique, used on all longrifles - including the Hawken Bros, trained by their father, Christian, in Maryland.  Next, is the outer end of the rod:  for .50 caliber and above, I start with a 7'16" rod, and taper most of its length to 3/8", so the ramming end has a flared tip, nearer to bore diameter.  But this is not at all necessary.  You can, if you are sane, ram a .54  (actually a .530") basll down the bore as easily with a 3/8" rod as with a 7/16" tip.  Lastly, anybody who tries to fit a boughten muzzlecap lto a stock is nuts.  Make a cap to fit the existing relationships.  All shown in my book.   Regards,   Peter A.
