ok after 2 weeks dealing with this thing I finally figured it out. Took a 22-250 piece of brass and everything fit the bolt. Hmmm time for investigation here is what I found out the savage target action comes only with 473 boltface I didn't know that. So another 30 bux in parts to get this action set-up for 378 boltface and it aint easy to get the parts. Seems Brownells had every part but one and it takes 2 months to get but I can get it directly from Savage.

For some reason Savage will only sell the botlface to an ffl but Brownells will sell it direct.

thanks for the replies all appreciated
