If you like 5's & they work for you----Why change?Here's my opinion on #6's. I've used #6's & have killed gobblers with them. They do work. But when I've cleaned the birds I've found pellets next to the skin that didn't penetrate. Just little balls of feathers. What good are the extra pellets if they don't pentrate. Shells were Federal turkey loads--copper plated. Both 2 3/4' & 3" shells. The shots were not long range 30 -40 yards.

I use #4's. My 870 likes them. I've never found a #4 wadded up in the fearthers.

Stick with the 5's---they work for you---don't reinvent the wheel. CB
