Don't know if anybody remembers the articles in the PS publications about Bruce Artus (from Pueblo, CO) trying to get a pr. dog at a mile or two, but his latest project is the .408 Chey-Tac necked to .378. He's researching and building one for a LR hunter on a Granite Mtn. action. He anticipates 140 gr. or so of some super slow burner (I'd imagine), in some-such long-barrelled rig. If anybody's interested he can be reached at 719-547-0340. I've seen some of the 100 yd. groups out of his big 30's and 33's that go right around 1/4"-- not bad.
