Re: 338rum factory gun?
If you purchase a rem 700 it is as simple as installing a 4" wyatt's box mag as I did with my recent build . A gunsmith should to this for $50 or so , I did mine with a Dremel tool and a tungsten carbide bit . My OAL for my handloads with a 300 gr. Berger elitehunter is 3.910 . Buy not seating the bullit so deep it allows me to load 92gr. of powder and not be compressed!
