Finally found the time to put this together. Built a 7mm Long Range Magnum, a wildcat developed by Gunwerks based on the 375 Ruger, necked down and shortened by 0.080" Materials: Remington 300RUM action. On taking it apart, it was apparently accurized. McGowen SS Barrel, D5A contour, 1:8, 26", Threaded muzzle The McGowen has a deep chamber throat for long VLD bullets. 4 port muzzle brake by Nathan Wright MDTTac TAC21 chassis, 3.715 Magazine well LuthAR buttstock on fixed buffer tube DPMS AR Grip Weight, as shown: 11.3 lbs, 2 lbs heavier than if I had gone with a light composite stock. A Leupold Mark 4 ER/T for glass. While waiting for parts, I kept my eye out for 7mm bullets. Found 700 Nosler CC 168gr at 32¢ each, and 400 Cauterucio 189gr & 172gr for 40¢ each. Making the brass is a major PITA. When I need more, I think I'll just buy some from Gunwerks. I'll take her out this next week and post a range report. If I really like her, a Jewell HVR trigger will be the next enhancement. Since she looks like a Franken-gun, once I'm done practicing, I'll do a camo paint job.
