Well, I got my Handi back from H&R yesterday. I'd sent it in to check the barrel, whcih wasn't locking up correctly. While it was there, I got them to go ahead and fit a .223 barrel to the frame. Anyway, they sent the gun back and included a test target that had been fired with the .25-06, which measured around 1/2" center to center.
Anyone else receive a test target with their barrel? Oh, they didn't include a target with the .223 barrel, just the .25-06 barrel.
