I got my kid a proof carbon prefit for his tikka for Christmas. The barrel is chambered in 6.5 prc. Out of the box the barrel looks awesome however when we spun the barrel on the bolt would not close. We didn’t even torque it to spec. Just spun it on to take a look and the bolt failed to close. It seems to me to be a head space issue. Any thoughts? Am I missing something? Thanks

Bolt won’t close with or without a round in the chamber?

Sounds like the tenon could be a little long. I think the tenon length is about .980” IIRC

With my calipers I’m getting more somewhere in the area of .999 for a tennon length. Will it effect my chamber if I have a smith remove that much material from the tennon?

Copy, thanks for the advice fellas. I’ll give them a call. I got the barrel from evolved ballistics. They were great getting it to me. Hopefully they will continue with the good service. I’ll advise

Talked to proof and they emailed me a ups slip. They had me send the barrel and action to them. Great service!

Interesting. I was just talking to a buddy today about our twin semi custom tikkas in 6creedmoor (I know cute 🥰 right??) which are mated to the actions… I was wondering how the prefit option would work on tikkas as all I buy anymore are Bighorns. Please keep us informed as I was just planning on my first tikka prefit as I’ve done savage and Bighorn/Zermatt prefit and shouldered prefits up to this point.

Just got my very first prefit ( I do all my own work normally but didn't have a 338 Norma reamer) it was a Mausingfield action and PBB prefit. The headspace was perfect. Very impressed with both ARC and PBB

I sent the barrel back and they double checked their measurements. Their barre was spot on on. It was my action that was slightly off. I got it all worked out and the barrel is a shooter. My kids took his dirt mule deer with it this year.

If he had i rebarreled, he probably messed with the action. Tikkas have the tapers at the barrel abutments
