Small Hevi shot in turkey breast = cracked tooth, dental implant and $4,000 bill.
After many years of shooting Federal copper plated 4's I went to Hevi for about five years and now I switched to LB #4. I get 120-150 in 10" at 40 yds. Still plenty enough to consistently kill a bird but fewer and bigger pellets means less pellets end up in my mouth. Trust me, those little, hard pellets are tough on teeth and I am surprised more people don't talk about cracked teeth on OG.
Good luck and keep your shots high if you go with Hevi Shot.
