Well it seems us double barrel-waterfowl guys are backed farther into the corner with the bismuth situation. Sure- we can shoot Kent TM matrix loads if we can find them and the gun can handle the pressure, but how about older double guns designed for 7000 psi or so? Are there any viable alternatives for nontoxic shot- for reloading to low pressure? Please I'm not interested in hearing from the very wise boasting about laying in a good supply of bismuth. Just looking for alternates for us that aren't as smart.
