Hello im new to the forum and looking for help building a long range rig. I have narrowed my caliber choices to a 7mm rem mag or a 300 win mag. This rifle will be for hunting and target, hopeing to work my way out to at least 1000 yards. Ive shot both calibers and like them both. The game i will be hunting will be deer bear and elk. Hoping to go out of state soon for elk and i dont want to see a nice bull walk away because i cant make the shot. I bow hunt elk in my home state of oregon. Looking to go to idaho and Wyoming in the next year or so. So i dont know if i should go semi-custom or all out custom. It would really help me if you guys could post some of your builds and specs parts loads. Just trying to gain some knowledge on which direction i should go. Rifles i've look at are remington sendero for a factory build up and for a custom i was thinking rem 700 action. Then sending it to pac-nor for barrel and action job. Any help would be awesome.
