You should try and get out and pattern those loads before you go hunting. So you know what the pattern looks like at different yardages. Every gun, choke and load are different. Even two of the same gun and choke setups will shoot the same loads different. Those loads should do the trick on a turkey though. I use to use 3" #6 out of my 870 and had a pattern the size of a papper plate a 40yds. They would realy lay them out. Now I do it the hard way. Nothing but bow and arrow. Becareful it can turn into an addiction.
