My understanding is most premium 00 buck was designed for cyl bore.
Premium buckshot has a shot cup, buffering added to keep the buckshot from deforming against one another. Please explain what feature is present, not present, that indicates the manufacturer "designed" it for cylinder bore. How would a shell be "designed" to be used in a modified choke? Explain please.
Sometimes you get what you pay for, sometimes you only pay more for what you get.
Three shots are not a "group"...they are a "few".
If the Bible is the literal, infallible, unerring word of God...where are all those witches I am supposed to kill? (Exodus 22:18)
