T3X Head Space Issue?
I recently bought new T3x superlite in 6.5 creedmoor; I have what I think is headspace issue but not sure.
The bolt cycles smooth without ammo but when I went to break it in I found heavy bolt lift after firing; I had taken apart and fully cleaned the weapon on purchase to include the bolt
I also noticed fired cases had scratches from chamber near base in circular pattern; I fired about 20 rounds total using two different factory loads; Hornady 147 ELDM and Federal 123
Both have same issue and the empty brass I hand loaded does same thing; there is some resistance of cases when inserting by hand at las 1/2 inch and the heavy bolt lift for fired and unfired seems very odd
I reached out to Tikka support via Berretta USA got my auto response a few days ago but nothing more from them
Anyone else had issues like this with brand new Tikka?

Hi two people that I shoot with have had to return there tikka’s for a refund, one was a .22lr that didn’t have its crown machined correctly and the other a tikka tac that had its thread on the muzzle machined out of true with the barrel

Thanks for reply; have not heard back from Beretta the importer as Tikka USA website has no support information, got my auto response of we will get back to your shortly a few weeks ago. I think I will just fix the bore myself with a little mild polishing and test it again.
Too bad really as it balances so nice and the 6.5 Creedmoor is such a nice shooting caliber. I had a gun smith add titanium nemo arms muzzle brake to test also mostly for reducing muzzle rise
I had Ruger American go wild 6.5 before this and rifle had bit heavier profile barrel; shot great but wanted stainless steal and this has much better balance for me

FYI:
I got impatient waiting for support RMA; polished chamber my self; removed bolt and did this:
Step 1:
Took wooden dowel 3/8′ thick and cut 1.5″ slit on one end with thin Dremel about 1/4 inch deep and small piece of tape to hold it, the dowel was about 12-13 inches long. Cut wet/dry 400 grit 1.5″ wide and rapped it till it was just smaller than large end of a fired case; so .460 roughly using my digital caliper; put my dewalt drill on end and spun on end till ran it in and out carefully and slow about 3 times
Note Cheap popular dowel; broke dowel in middle as my paper winding was a bit too thick closer to the .470 inch ..fun getting paper out but did very carefully as it was fully out to walls and removing dowel left it lining the bore
Sand paper wouldn’t pull out so I used very long very skinny flat tip screw driver to collapse the paper on two sides slowly as to not scratch chamber till paper was touching in middle and then used cleaning rod very carefully on front to push out paper while holding paper in middle on receiver end and paper popped out ..this may have not been best way to start but I wanted to take any high spots out
Step 2:
Youtube showed person using soft scrub with bore swab; did the same with drill on one piece of aluminum cleaning rod, the bore swab I think was .45 caliber and ran that in and out 6-7 times; they used a swab and really fine steel wool wrapped on swab for next step but I decided to use Flitz instead
Step 3:
New bore swab and ran green Flitz polishing liquid for final 7-8 in and out gently
Step 4:
Cleaned with brake clean and then used CLP
Step 5:
Tested today and it worked like a champ …night and day difference; 3 test factory Hornady rounds look great no more scratches or heavy bolt lift after firing; would have done a bit more Flitz if needed guessing the key is to not over do it and go slow and easy I tried to be very careful on depth so as not to hit shoulder of neck
Saved money not having to ship this back if I ever got and RMA as requested to Beretta USA the importer
I would have preferred to have it RMA’d as the rifle was brand new and $899.00 but hunting season is almost and I already had gunsmith add 1/2×28 threads and small titanium muzzle brake
