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.

First trip to the range today in months.
I had intended to fire form cases and chrono loads. I left 1/2 of my loaded cartridges back home.
Short of it is, 71gr RL26 under a Sierra 175 SPBT, 3.355 OAL, yields 3000 FPS, No sign of pressure yet.
The recoil is less than my Ruger Hawkeye 7mm-08 mountain rifle.
