Well, I'll be honest... I couldn't shoot prone.  I do best on the bench because I don't bend and move so well anymore.  I do hope to increase my accuracy once I start shooting cast.  My bore is pretty beautiful... no pitting, very bright and nice defined deep rifling!  This rifle has not had much use over the last 90 or so years.  I believe that I have fired more through it than anyone else.  It's history is quite remarkable!
