If your rifle is now shooting 1.5" with factory ammo I'd be willing to bet that when Hill Country does their thing they will have it shooting that 0.5" they promise and will even tell you what to use that will do it.
I don't know about that... After reading about the service, they only lap the lugs and lug recess if there
isn't a possiblity of it changing the headspace. In other words, if the headspace will be too much after lapping, they aren't going to do it. Just about every other place I've talked to will lap the lugs/recesses and check headspace, then, if needed, they'll pull the barrel and cut a thread off and set the shoulder of the barrel back to make the headspace minimum.
So if they aren't lapping the lugs/recesses and/or squaring up the bolt face and barrel, and it's obvious that they aren't going to do that if they won't lap the lugs because the headspace will be too much, what exactly are you getting for $400?
Here's a basic tune-up as I understand it:
1. Check headspace for a standard on that gun, and shoot it to establish an accuracy standard.
2. Pull the barrel and square it with the receiver and bolt face on a lathe or CNC.
3. Lap the lugs/recesses to get around 85%-90% contact to keep torque from backthrust to a minimum.
4. Re-install the barrel and check headspace, if not enough or if it's too much, pull the barrel and make the adjustments to get it right.
5. Re-crown the barrel.
6. Make sure the scope mounts are level and square to the receiver.
7. Tune the trigger to what you desire or to what's safe.
8. Bed the rifle to the stock.
9. Shoot it with the control load to see the improvements.
Here's what the website says:
How We Do It:
HCR’s Accurizing includes complete inspections of your:
Barrel and chamber with our Hawkeye bore scope
Locking lugs
Stock
Scope
Trigger
After a complete inspection of your rifle:
Aluminum Pillar and Glass Bed your action
Recrown the barrel
Clean and adjust the trigger
Ensure even locking lug contact if head space allows
Lap Scope Rings for Concentricity
Reading that tells me that you're getting a glassbed job, trigger job, and lapped scope rings for $400 (if the rifle will shoot less than a MOA afterwards) or for $300 if it doesn't meet the standard.
Contrast that with the work that a smith about 80 miles from me will charge:
Pillar bed $45
Trigger job $25
Re-crown $25
Lap lugs, headspace, square and install barrel $105.
Mount scope and sight in $15 (with your base and rings)
Refinish the entire barreled action $50-$150 depending on finish.
So for what you're going to pay a MINIMUM of $300 for, I can have done for $105, and for under $400 I can have twice as much work done.
