Ok so its not a PPC its a 6.5 Grendel but its the parent case. Ya I have wanted to do this for a while now. Its pretty easy. I am posting up photos below if anyone else wants to give it a go. The bolt is one I have fluted, bushed turned up and done a bolt lift kit on. Now its getting another barrel this time for 6.5 Grendel. Naturally its not the same bolt face as the 6.5x47 so a 223 bolt head was acquired with the ejector claw and plunger. Get the ejector claw for the 308 size not the 223. Pretty easy to open up the bolt head and true it up. I also bushed it to so it fits the old firing pin witch has also been bushed and turned down to a smaller size. The extractor claw was tricky and I use a big magnifying glass and DRO to know what is getting cut on that tinny part. It took some time back and forth on the mill but I got it right. Next one should be a breeze.
