Good point!!#7 TSS is WAY overkill for turkeys. But I understand that's what Federal released originally, and people have killed a bunch of birds with them. You just give up pattern density for no reason with #7 TSS, as they have far more energy and penetration than needed for turkeys.
#7 TSS penetrates like lead B's; 1.5" penetration at 103 yards.
On a tangent. I suspect Federal first released #7's because they thought there was no way they could convince turkey hunters that #9's could kill birds.
Edit: When I refer to TSS, I mean 18 grams per cubic centimeter weight tungsten shot.
I've been buying 18 g/cc shot from Hal for a long time; his new website is Super 18. He's great. You get EXACTLY what you ordered, and he's extremely responsive. He gives you load data when you purchase, he just asks that you don't share it.There is a guy that sells TSS components packages for 15rounds. Super18tungstenshot.com but you'll need to buy powder.
I can buy a turkey poult for $15. And raise it for about $30 in feed.I saw some turkey loads at Sportsman's last weekend and had to do a double take... $70 for 5 shells!? If I turkey hunt this year, I'll stick with archery.
