[Catuto]

I have a Remington .338 win mag XCR 2. I useRemington ammunition 225g core lock . Sometimes the bolt gets stuck for a fewseconds until then opens a few attempts . I can fix it? And How can I fix it?Is normal? Is dirt?

Sounds like you might be building too much pressure. How old is the gun? Maybe call remington customer service and relate the problem since you are shooting factory remington ammo.
