Thanks, Yondering, that's what I thought.
What is your opinion on using a standard 7.62x39 bolt with the longer firing pin vs using one of the Young's bolt that accepts a standard length firing pin & supposedly beefed up lugs?
Is Black Hole the only source for that chambering, as I've not seen it elsewhere & I know that BHW designed the reamer for it.
Their lead time is generally pretty long, but since this would be a winter project, it really doesn't matter too much.
