I am rebarreling a 700 for my dad. Going to a 6.5 prc. I take out the ejector pin and firing pin. Use go-no go gauges. Have everything set perfect. Fire a round or two doesn't matter factory ammo or reload and cannot get the bolt to pull the casing out of chamber. I'll then drop in the no go and bolt closes. There's maybe 10 rounds down the barrel in total. I have another barrel in the same caliber from the same company on a tikka action, it doesn't have the ring in the chamber. I didn't look for this ring before installed the barrel the first time. Could it be possible this happened after 10 rounds? I'd rather not mention company names, not here to bash anyone. Just looking for explanations. Thanks
