I really like the .284 Winchester cartridge although it isn't any better than a 7mm-08 which is more popular. My only problem is the standard length action of the M48 is better suited for cartridges with a length of 3.250" as compared to the .284 which has a length of 2.80". Your going to have to have the magazine blocked to get proper feeding. If it were me I would look for a short action laying around to build a .284 on. Lawdog
