So ive been considering making a custom remington 700. Ill hopefully use this rifle to begin shooting long range as well as an occasional hunting rifle. I was thinking about 300 win mag or 300wsm. Im going to dublicate a 700 stock from black walnut, finish reaming the barrel and fit it to the action, glass & pillar bed with free float barrel, and do some trigger work. What else should I look into doing? This will be my first bolt action total build and im going to take it slow. Is the 300 win mag good for longer ranges? I do handload and have a fair understanding on the basics of long range shooting. I am still learning but most of all I need some experience and a whole lot of practice. I am hoping to top this rifle with a nice scope besed on the mil system. Ive been looking into the bushnell elite tactical scopes. Can anyone recomend any other good scopes.
