Nosler Sporting Handgun Bullets 45 Caliber (451 Diameter) 185 Grain Jacketed Hollow Point.
The most accurate & economical .45 bullet that I've found.
The ammo caught my eye too. Shot a few into a pig carcass on a friend’s farm. (Penetration testing can be fun) Went right out and bought a couple of boxes. I love the old Colt Commander (alloy frame). I sent a letter to Colt w/serial number, they said mine was built in 1953. Saw it in a shop back in 1972, had to have it.
