so question. i spoke to a old guy at sportmans warehouse today. he spent 20 years fiddleing with falling blocks. so he sai that 1 out of 5 are accurate. he said its due to the forend piece pushing against the barrel. he said it could be as bad as 2 1-2 groups at 100 yards. is this try? cause if a guy had the skills and scope i would rather hear it can do 4 ubch groups at 600 yards. thoughts?
