WCChapin | Remington Revival – First Fifteen Firings from the 6mm Model 788 Donor Rifle
William C Chapin
Trying out the Remington 788 “Donor Rifle” that was featured in my Rifle Forensics video.
At some point durning the shooting, the camera at the bench stopped recording, and I don’t have footage of the full second group of 85 grain bullets – and none of the 100 grain shots were recorded. I do have target camera footage documenting all of the shots. I still have five of the 100 grain rounds to try another day!
