Looking for some guidance. My son is turning ten this spring (legal hunting age in MI) and has saved up for three years to buy his first duck gun. He has bought a beretta 391 urika 2 youth model in twenty guage. He has been shooting a .410 for two years or better and is a pretty good shot. I want to buy him a case of ammo, for his birthday, that he will be hunting with so he can shoot some patterns and try to break some clays with them over the summer before the season starts. I don't reload so I am going to be buying shells off the shelf. I want him to have the best chance of killing birds realizing his shooting will probably be marginal. My question is this, I was looking at the remington hd shells, they have a 3" 20 guage in six shot 1 1/8 oz load. would this give him a higher pellet count than #4 steels in a 1 oz load? I can not find pellet counts on the factory websites and the higher density of the rmington hd leaves me scratching my head as to how many pellets are in 1 1/8 oz's. Also do you think the 3"ers would be to heavy of a load, he's only 75 pounds or should I be getting him the 2 3/4"ers. I know I can get the birds close, we never take shots over thirty yards, so range and tight patterns are not the issue. I want to know what off the shelf load, with the widest choke is going to give him the best pellet count with good knock down power to 25-30 yards? This year money is not an issue. Next year he is on his own. Thanks guys any other advice is welcome also, how are those beretta factory chokes?
