Tinker,

Yes, Herr Denig's barrels pass Nitro Proof easily. There are some other barrelmakers who build Damascus barrels the raditional way - one mroe in Germany, one in Sweden and one, I am told, in the USA. I hope to post their information here as I find it. Nowhere else would this be appreciated as much as it would be here.

BTW Herr Denig teaches Damascus barrel and knife making if someone is interested. He is past 70 years now in age and I hope that someone who is interested in his techniques which he rediscovered through research takes the time to learn and use them. I am personally all toes or else I would rather learn this craft than continue on my present geriatric education.

Good hunting, my friend!
