    Not a review but my experience with the 50 Beowulf. Thought about adding my findings on a Shorter firing pin vs Rifle primers with the 50 Beowulf, and even some tips on leaving material for strength if your machining the receiver from a blank. How about the amount of material to take off a stock upper ejection port and retain the factory dust cover. The amount of weight that works perfect for the buffer, but F it your on your own…

  2. The 50 Beowulf rocks!!! However a heavier buffer is recommended (Not required, but recommended), and that goes for all the heavy hitters, like the 450BM, and 458 SOCOM.
    The Beowulf kicks like a fly weight 20ga with high base slugs! Hurts sooo good! Decent optics are a must if you want them to survive. The Aimpoint 9000sc is perfect for the Beowulf, and I personally have one mounted on a Burris PEPR mount.
    If you decide to buy a big boy upper you best reload if you want to shoot it regularly!
