Thanks Dog Down, Have You Had Any Issues With Your Rifle Not Chambering different ammo. I don't have any reloading equipment so I stuck with buying all ammo. It wont chamber Hornady match 168,only ammo I shot that never had one bullet issue was federal 150, but had Chambering issues with fiocchi 150 not all would fit. Its not hitting the rifling cuz the bullet don't have the grooves in it if it was.
