What more can be written about the 30-30 that hasn't already been written, rewritten, sliced/diced, and examine in excruciating detail by dozens of writers over the past 121 years?
That is the best piece written about the .30-30 in recent memory.
(That coming from myself who views the .30-30 as a rifle loony's premo test bed for all manner of experimentation with cast and jacketed bullets, in bolt guns and lever guns.)
