PTG Bolt Head and Bolt Body: What Fitting is Required?

Hi Folks

I have a Savage 12 Benchrest in 6mm BR. I have ordered the following and will receive them early next week:

Criterion 30" Bull Barrel in 6mm BR
PTG bolt head
PTG bolt body

PTG makes vague references to a need for gunsmithing to install the bolt head. I believe they just mean that I must do the headspace measurement with this assembled bolt, but I am not sure if I need to do more. I have emailed them, but no response.

I do understand that I need to set the headspace with the new barrel and bolt, and I have the GO gauge (and will use the tape trick for NO GO). I have installed a Criterion barrel before, successfully, on my .308.

Anything else I need to do for this job other than setting the headspace with the new barrel and the bolt with the new body and bolt head? I would think that with the floating bolt head design that lapping the lugs should not be necessary, but I am often wrong.

Thank you!
Michael
 
Michael,
I just rebarreled a savage target in 6 BR with a PTG bolt head. No fitting of the bolt head was needed.
I like to cut the threads with a shoulder, like a Remington, so I didn't use the nut. I find it easier to get the headspace right that way. Your mileage may vary.
Regards,
Ron
 
Thanks Ron

I have already done one Criterion barrel install on my .308 and it has been working great, so since it is a method I am familiar with I will stick with the barrel nut. I did order a precision ground barrel nut and recoil lug for it (same as on my .308), and I have the action vise and barrel nut wrench and GO gauge, so I will just do it the barrel nut way.

I do appreciate the advice though!
