I recently "inherited" an older Savage model 840 rifle from my fiancee's uncle. It is a small gun with a short barrel, in relatively decent shape, chambered in 30-30. It has a removable magazine, and a fixed 4x scope. Now, I have read a lot about Savage, and even own a Model 110 in .223 for coyotes. But I have never even heard of this one. Is there somewhere that I can find information about this gun? Does anyone know if I can change out the barrel or replace the stock with one of the aftermarket jobs available for today's rifles? I was thinking I might be able to put on a .221 Fireball or .17 Remington barrel on it, and make it into a small critter gun. I would imagine I would have to find a different magazine as well.
