I have a Yugo 8mm that is about a 4 inch gun at 100 with factory irons.

It should do better than that, the bore is pitted. I did recrown it, with no change.

Anyone know where to get a 762X51 or 308 barrel for it? I have rem 700s but they are too small to fit to the receiver

Thanks

How about new?

Brownell's, $83.99

Plus the headspace guages, plus the reamer, plus the blue job.

Yep.

I have headspace gauges for every caliber I shoot whether or not I intend to install a barrel for it. Damn useful when buying used Mausers.

Reamers can be rented, borrowed, or cost averaged over multiple guns.

Personally, I either install SS barrels or finish with Alumahyde II.

If you can't take the heat, don't DIY.

I'm in hell and need ice water. In any event try E.R. Shaw. They're not that expensive and do a pretty good job.

Try Allans Armory he shows about a dozen Mauser 98 take off bbls in .308

My gunsmith may have a few. How much you want to spend?
