And dont know what to do!!

I have a couple vintage guns I like to hunt with.

One a Model 12, and another, a Model 21.

I have used Tungsten matrix as a non tox alternative in the past.

I have read that TM will be harder and harder to find.

Bismuth is next to impossible for me to find.

What are you guys that shoot old guns doing to prepare for Hunting with Non tox?? Its inevitable that lead is on the way out!

I am also somewhat concerned about the pressures that Tm loads carry! Mostly for the 21. Do I worry to much??
