Took my BYF 41 to range today. Put 20 rounds thru it at a 100 yard target. Didn't score a single hit!!! I am a good shot, and proved it to myself by immediately putting 10 of 10 on target with mosin m44. The bore is VERY dark. I can see rifling and it does appear to shine a little. In between the rifling it is gunked up bad. The missed shots weren't just a few inches, they were multiple feet. I think one round fell 10 feet short. Is this the bore or just a terrible rifle.
