i know this has been discussed lots but i can't the search function to ever work properly for me. i'd like to build a .30-40 Krag double. either by sleeving a smoothbore or complete new barrel assembly. does anyone know which the proper actions are to start this on? i see brownells sells a book that guides you all the way through, and i will buy that someday. i remember someone mentioning it's best to have a cross bolt locking system. whats out there for reasonable priced actions? i know it won't be cheap, but i don't plan on buying a Rizzini or a Beretta as a starting platform.
