Congratulations, and welcome to the club! I loved my 22 WMR so much I bought another one! Mine is also XT-22M, but with the standard taper barrel, wood stock, and topped with a Bushnell 3.5-10x36 scope. It is a nail driver with CCI's 40 grn SGB. Blue murder on 'chucks and crows out to about 110 - 120 yards. Much farther than that and it gets a bit sketchy. My second WMR is a Henry standard, and it wears a Marble's front bead (custom job) and buckhorn rear sight, both from a Marlin 336. A fine shooting rifle, for sure and has taken varmints out to 75 yards so far. Those sights are a marked improvement over factory. Hope you enjoy your new rifle, it sure is a looker!
