I have a Remington Model 700 220 Swift in the Varmint Synthetic format. It has been an excellent shooter but has some throat erosion and is starting to loosen up the groups a bit. Since I have a 223 for varmints, I have been thinking about using the action-scope-stock combo and rebarreling the gun to make a long range hunting system. I was wondering if it is possible to convert it to a more potent short action caliber such as a 7wsm. What would I need to change to make it happen?? I am thinking that a barrel, a proper size bolt for the new caliber and possibly some magazine parts would make it happen. Am I way off or is it possible??
