I have been a member of this site for a year. I dont post hardly at all, but read everything I can about what y'all write. I want to build me a long range rifle, but dont have unlimited funds to do it with. I reload and have for several years. I own several different rifles 3 rugers in 257 roberts, 30-06, and 300 win mag, 3 rems in 25-06, 30-06, and 7rm, 1 custom in 22-250, and two win m70 in 300wsm and 270. If you were gonna build a long range rifle would I be better to start with one I already have or start from scratch? Right now I shoot out to 400 yards, but would like to increase my range. I have thought about buying a sendero and setting it up for longe range, is this a good idea? I appreciate any help.
