The federal flight control would be your best choice for that gun, I assume you have a 2 3/4 inch chamber. I have an old Remington Sportsman 58 with a fixed full and have killed several toms with the Federal FCW lead #6s in the days before the heavy load was available. I would suggest that he try the federal heavy #7s for the most effective patterns, I would guess that gun with that load should be capable to nearly 40 yards with out a problem.
