I've got to thank George Mann for the nose job on one of the barrels.
I just loaded some 158 gr. XTP FPs over Lil' Gun. I ran three thru the chrony and came up with 2296, 2287, 2293.......no pressure signs. I'm not sure that this may be too quick for that bullet. It's raining pretty hard just now, so I won't get to check them for accuracy. I'll know soon enough. I should make a place in the unused granary shed so I can shoot regardless of weather. I still can't get a line locally on any 1680. I'll be traveling in two weeks, so perhaps I can find some.
