Unhappy buyer by Jim L, Verified Owner, March 29, 2025
Ammo fired ok, however, failed to eject and jammed 10 out of 15 rounds. Switched to different ammo and problem was resolved. Rifle was clean and bolt was inspected for damage and none was found. Ammo was the problem. I don’t endorse this product

50 Beowulf round…..awesome by Edward Jonas III, Verified Owner, September 12, 2025
This is well built round, I had absolutely no problems with it. It feeds well, and worked perfectly in the 50 Beowulf rifle built. there wasn’t one dud in the box as I have been hearing has been happening. But these, you won’t be disappointed
