Had a couple of Tikka prefit from PVA using Rock Creek blank 3 years in 308win and 6.5creedmoor, not sure how much expectation should I set to? I couldn't get any group better than 0.5-0.6MOA, most time are 0.8-1.1MOA during load development seating depth test. Should I be worry about the accuracy or maybe that's me?
I am hand loading using quality components and can get single digit SD and low ES between 10-20.
Low/tight chrono numbers are only an indictor of a load but not a guarantee.
Many times when folks have problems with a barrel there's something else going on with the rifle. With a rifle that comes complete from a shop then it's on the shop to assemble everything and make sure there isn't something rubbing, long action screws, bolt handle touching the stock, trigger dragging in the well, etc.
Look for anything tight or rubbing on the trigger well, the bolt handle and the barrel channel.
Make sure the action screws aren't too long, especially the front screw. If it's touching (especially intermittently) on the bolt head you're in for a rollercoaster of "it shoots, no it doesn't, yes it does..."
Check to see if you have a carbon ring building in the rifle throat. That needs to come out.
Check to see if the crown drags fibers off a qtip. If it does then we need to recrown that barrel. This is becoming more and more of a problem with folks who aren't properly trained in cleaning a precision rifle barrel. Sometimes we screw up a crown but it's rare, less than 1% of a problem.
If you have a suppressor on the rifle take the suppressor and any other muzzle device on there off and shoot it without anything on the muzzle. See if it's really a barrel problem and not a brake issue.
And the old staples: Check screw torque, check base and rings, tracking check your scope.
If you've gone through all this stuff and you're still having problems then please reach out and I'll see what else we can do to assist you.
As far as answering emails and the phone:
@Rob01 hit it on the head. I don't employ someone to sit on the phone and answer it all the time. We do the best we can but if both Ben and I are elbows deep in something we let it go to voicemail. Continually stopping for distractions on a detailed task is a great way for things to get screwed up. When your barrel is screwed up do you want to hear "well we didn't miss any phone calls while we assembled your rifle".
No, you want to hear "I'll get back to their email after I make sure your rifle is correct."
Ultimately the responsibility for a high quality, safe product is with me. I do not babysit the phone, email or forums and let unsupervised work go out the door. The shop practice is that nobody checks their own work. If I cut a barrel then Ben inspects and gauges everything before it leaves and visa versa.
We stock "ready to ship" barrels in common calibers and common actions. If you're in a hurry (or just impatient) then don't order a custom barrel, order something that is sitting on the shelf and can ship the next business day. We pack, ship and get pickup from 3 major carriers 5 days of the week. Parts like brakes, bullets, barrel nuts, and RTS prefits ship immediately.
