All I can say is buy a sammi chambered barrel that comes with a matched bolt that comes from suppliers that have been in this game for more then a few months to a year and you should be fine.
Got to jp barreled grendels, and each of my kids has a bolt grendel one cz and the rest or howa.
And we have it to have any ammo stick in the chamber and between us we have used every factory load from hornandy,federal and PF plus some from nightop's and AA.
