I am in California which requires non-toxic ammunition for ALL hunting.  I am getting to the end of my Hevi-shot rounds...  Shooting 1 3/8 oz or 1 5/8 oz of Hevi-shot....  Full choke.
I have no problem switching to TSS but I do not want a 2 oz load...  I also am not excited about a duplex load.
Who makes TSS or a Hevi-shot type of load in 1 3/8 to 1 5/8 oz loads?
I typically shoot about 3 rounds per season...  I am in the field with 3 in the gun, and 3 in the vest.
Has anyone had issues getting any of these loads to pattern well?
