Just installed a x caliber remage 22-250 barrel. Used go no go gauges to set headspace, rem action was trued, after market recoil lug installed. Fitted to a bergara stock, dollar Bill slides all the way to the nut. 1-10 twist 5 r groves. Broke barrel in per manuf. 4 different loads, diff weights. Best group is 3 min. I haven’t called x caliber yet wanted to make sure I’m not missing something. Thanks

Plunger was pulled for headspacing. Extractor still in place. I just colored a bullet used my c o a l gauge and seated the bullet same Mark same spot
Gotcha. Seems like you’ve scratched the mechanical stuff off the list. If your concentricity is good there might be something funky in the throat. If you pull the barrel and hold it up to the light your eye will see a faint line where the freebore starts, depending on diameter. If it’s not concentric you’ll probably see it.
And make sure it’s not the barrel hitting the stock from recoil or bipod influence.
