I got mine for Christmas in 1970, and I have 198 rounds of original Remington 38gr Power Lokt's left.
About all I use it for is fall turkey, so I think I have enough ammo to last me, lol.
Back when I got it, I lived on 389 acres in N. Illinois, made up of woods and ponds, and shot lot's of stuff with that rifle. That Power Lokt bullet worked very well.
