Owned a 460 Wby, for a while, that I never shot.
Does that count?

Was out yesterday with my brother doing some shooting in a big slash. Just off hand practice with a few guns before the season. Between us we got off 13 rounds of factory 500 gr. 460 WBY. The 270 and 308 are quite nice after a few of the big ones. Apparently the 460 is zeroed as several 6" rocks at 100 yds. were powdered.
