Home Forums Hunting & Shooting Custom Rifles & Wildcats 7mm PRC Build Begins

Action, reamers, dies and gauges are in. Waiting on a Proof Sendero Lite that I'll finish at 22" and thread 5/8-24 for a TBAC Ultra-5.

For the stock I'm going to give AG Composites a shot and BDL-style bottom metal will be from Hawkins. Triggertech trigger.

Should have it wrapped up in a few weeks.

Following closely …

Been going back and forth on barrels for something very similar; been leaning towards the sendero prefit but still haven’t pulled the trigger. Actually wish it was 22 as you are doing.

21st century round and components. Cool.

OP, where'd you source the AG stock from? AG direct? Wait time?

Working with their external marketing firm on getting one since the build will be covered in an article. No guarantees at this point on whether they are able to deliver in time.

More to follow once I get a chance to shoot my 7 PRC build in ernest - weather has not been cooperating. Did send 2 rnds down the tube today, out the back door, so I'd have a couple of once fired rounds to send to Hornady and have modified case gages made.

Should be nice.
Wish y'all the best on your build.

For anyone interested in the defiance/proof prefit route, Altus is now out and Evolved ballistics is down to two.

Oh man... I can feel the boat moving now... It's getting serious

Following this build.

So is this (mesa) actually made by AG?

Yep. Hint............

👍

IMHO, no.

Switched further discussion over to the Mesa precision thread in the gunsmith forum. Probably should’ve posted there to begin with. Don’t want to derail OP’s thread and looking forward to his build.

Got a barrel in and a set of loaner reamers from Hornady. I follow the barrel fitting procedures outlined by William Hambly-Clark in his excellent book.

Looks like Imgur isn't working anymore, apologies for the photo links. This isn't a step-by-step but it shows the basics.

Started by dialing in the bore over a 2" section, shooting for around .0001" of coaxial alignment along that length.

Cut the tenon to length and diameter.

Threaded 16 TPI until the action slipped on. This was my first build using my Hardinge HLV-H, what a treat to run-- especially when it came to cutting threads.

Rough reaming the chamber

I didn't finish cutting the chamber yesterday since I was taking my daughter hunting, I will wrap it up this week sometime. After I confirm headspace, the next step will be cutting the barrel threads as well as a crown. Stock should be here next week and I can start bedding. Action will go to H&M for nitriding.
