Re: So you want to....
As with most informative write ups, it's not the stuff they show you that's difficult. Rather it's the stuff they foget to tell you about like using copius amounts of lube on the reamer that'll get you in trouble.
They also completely skipped over the now common practice touted by Gordy Gritters of indicating the chamber at multiple depths to ensure that the chamber is cut directly concentric with the bore. I bet they actually did that, but decided it'd make the article too long trying to explain it all.
Then again, the intent here wasn't to be a gunsmith training guide.
Like Wildrose said, definitely not for the average DIY'er. Yet, very personally rewarding though expensive for those who do their homework and succeed. If I do a couple dozen more of my own rifles, I may just break even. Nonetheless, having learned and taught my son how to build an accurate rifle, I'm thrilled.
