Thread: Ruger Ranch II Bolt face - do I have a problem?

I bought the rifle on TradeMe, and failed to do my due diligence and ask for photos of the bolt-face. So while I’m not certain of the cause, the seller did acknowledge that they used Winchester primers, which apparently a bad batch of is well known for this etching of the bolt-face around the primer perimeter.

The rifle shot very well, but the rough bolt face created brass shavings from cycling the bolt. It was still functional, but gave me the shits, so decided to get it fixed.

Mark bushed the bolt-face and was able to maintain the same headspace. I asked Mark to use Jim Borden’s method as per this link https://bordenrifles.com/wp-content/...g_pin_bush.pdf
