Not saying anyone's methods are wrong.  But I've had to shoot non-tox on public land for probably about 30 yrs now.  Maybe I have superior brain power (doubtful), but I've never found it hard to keep straight.  If I think there's a chance I'll wander onto a WPA or GPA, bismuth.  Anything else, lead.  Lead being superior & less expensive, I just find it impossible to NOT shoot it where I can.  Plus, I enjoy having different loads to consider, shoot, obtain, test, etc.  All part of what I love about pheasant hunting.  I hate cardboard shell boxes.  They fall apart & are hard to cram shells back into.  So all my shells go into clear Ziplocs.  Makes swapping out shells in my vest pocket quick & easy.
