Hello everyone, my name is Cody and I'm very new at sniperhide and not very familiar with navigating around, but slowly learning it.. I have recently got interested in shooting rimfire matches and nrl22, I have a cz457 in a krg bravo chassis with 16.5" non mtr barrel. And athalon midas tac scope.. i replaced the barrel to a 20.5 lothar walther barrel. Seems to be a lot more accurate but made the jump to order a rimx action and i don't know anything about them hardly, so i need info on getting a barrel for it. I appreciate any and all help or advice
