you shouldn't see a difference, I always shoot cheap stuff even dove loads to get basically sighted in.  I'd suggest getting your POI/POA dialed in at 20-25 yards then for your last shot and pattern clean your gun and shoot one Hevi 13.  I once had an IC choke that always shot low and it did it with all the loads so IMO it's not going to be much of a shell to shell factor out to 40 yards.
