Had a .223 years ago with headspace issues....

My buddy has a .223 that shoots lights out, he also has a .243 that won'thit a barn wall from the inside, with100 grain bullets. He just bought a .17HMR that I shot a half inch group with at 100 yards yesterday, and was pickin' apples off a wild apple beside my range at 150 yards.

My wifes scoped20 gauge rifled barrel is a wicked mean lil' bastid on deer...........
