I want a .404 Jeffery badly but just can't afford a new or used one. So far I've been downloading a .416 Rigby to approximate .404 specs but it just isn't satisfying my lust. Recently I've been offered the opportunity to purchase a used wooden stocked Remington 700 in .300RUM for a few hundred dollars. I thought being the .300RUM is based on the .404 case I could simply rebarrel, open up the barrel channel, then reinforce the stock and have my own poor man's .404. To me it sounds reasonable and relatively easy. Am I missing anything that might rear it's ugly (read expensive) head somewhere along the project?
