Proof Research .284 16.5" 1:8 Bolt Action Rifle Barrel

Sixteen and a half inches of .284 bore from Proof Research, cut for a bolt action and twisted 1:8 to handle the heavy 7mm bullets that people build these rifles around. This is a deliberately short tube. Hunters who run a can in timber and shooters who want a rifle that fits a pack scabbard both end up here, trading a slice of velocity for a gun that does not fight them in tight cover.

The 7mm bore has quietly become one of the most useful diameters in the catalog, with bullet options that cover everything from light varmint weights to long hunting projectiles. Proof Research holds tight bore and groove tolerances across its line, which is the part of barrel making that actually shows up on target. Check the chambering and shank against your action before ordering.
