I I'm starting a new build and I'm not sure what direction i want to go with it? I have a Remington 721 action that i milled out to accept a 700 trigger and safety. I havent decided on a caliber yet and was hoping for some input. Gona be for long range targets and hogs. I want to put a short barrel on it , 18-22". Bbl will be heavy sporter-heavy. I have a dozen different cartridges in mind but cant nail one down.
