I have a XR-100 223, these guns are target guns w a 40x trigger and barrel, mine will shoot a one hole group at 100yrds all day, If u can get one id grab it because they are hard to find here , iv never seen another one.
I use 95gr NBT or 95gr Hornady SST over 35gr Varget out of my Rem 700 CDL-SF 243 and Rem 7 Predator 243, They both shoot extremly well, And Noslers and SSTs are easy to get and coyotes dont walk off w those.
