That's good stuff! I think you take just about any knight and put 90 or 100gr pyrodex and a .240 to .260 saboted bullet and have a real shooter. Everyone I know that has one shoots something in that range, and they all drive tacks. Both mine will cut one big hole at 50yds if I do my job.
Interesting about the spent caps left behind and not firing the cap. Didn't you say the last time that the cap went off, but the charge didn't go?
