I’d go with the Heavy Dove load, according to the box same powder weight but 1/8 more ounce of shot. Squirrels hide and muscle is fairly tough. Frequently a full blast from a shotgun only results in a single, maybe two pellets getting thru to do the damage. That extra 1/8 oz of shot might make the difference. Wouldn’t use the Turkey load, even though it seems a bit light for turkey, it still is designed to blow the head clean off a 20 lb bird. It might be too strong for squirrel. Either way, good luck to you both.Its been years since i've been out squirrel hunting but i'm going to take my son out this week.
I'm going through my old stash of #6 shot and figure any of them should do the job, but is there one of these 3 boxes that I should use over the other? It seems odd to me that a dove load would have more powder that a squirrel load
