This cartridge has some amazing traits that I had never experienced before; one of which was that it is very forgiving. Whether my powder charge was 83 grains of R22 or 85, it was difficult to shoot out of a hole. The powder charge utilized above is 84.5 grains of R22 with a chronographed velocity of 2780 fps and a validated velocity of 2770 fps. The extreme velocity spread is… (You won’t believe this) three feet per second...
Richard and I called wind for each other at two distances, 1536 meters (1680 yards) and 1574 meters (1722 yards which is 38 yards short of one mile). I would have taken pictures of the 1536 meter 10” groups, however the climb was impossible.
This cartridge is a BIG winner because it is very accurate, a winner because it is very forgiving, a winner because the cartridge is very efficient and the bullet stays in the powder cone, a winner because it works in the Remington long action receiver, a winner because the bullet can be seated to the correct seating depth and still cycle through the action, and a winner because the bullet doesn’t enter the transonic region until approximately 1,750 yards. When it does, it’s moving at 1,306 fps, with 1,136 foot pounds of energy. This may be one of the most unique cartridge designs of my time. No; it is the most unique cartridge design of my time.
