I bought a 591 for my woodchuck rifle in 1979. It shot fabulous with the Remington 38 gr. HPPL ammo. Killed a truckload of chucks, some rabbits and squirrels and a couple of deer with it. Sold it along about 1983 or 84 when I ran out of ammo for it. I'll never forgive Remington for discontinuing the ammo so soon.
