I would like to build a rifle to basically turn into a hobby and start reloading. I would start with a used rifle for an action and would prefer a beat up Remington 700 to start it off. I would be (over a period of time) replacing the barrel, trigger, and either build up the existing stock with body filler for shaping/modifying and bedding it or buy an aftermarket bedded stock. What kind of advice could you give as far as what action, trigger, and barrel combo would best suit me. I have no idea where to start with a barrel or the finishing of one or if you just order one and screw it on. I had a Remington 700 SPS tacticool in .308 that did well up to 800yd but i was always wanting more out of it and had no idea what direction to go. This gun would be a "range queen" so weight is not an issue. I would like to stay with a Remington .308 because it is what i am familiar with but I am not afraid to explore other calibers and actions. Thank you in advance
