I just ordered a 8.5 twist 7mm Brux fluted Remington varmint contour I’m thinking I’ll have the smith finish it at 24 inches. I’m looking at a Orgin,Stiller or Mack Bros action. I keep thinking a orgin because of the medium length option. Stock either a Grayboe Phoenix,AG composite or Manners. Im wanting around a 10lbs hunting/steel shooting rifle that will shoot 168-180 grain bullets around 2900-2950fps with good accuracy. I keep coming back to the 7mm SAUM. I know brass can be hard to find at times. But so is brass for many of my other rifles and when it’s available I try to buy 300-500 pieces at a time. Thoughts?
