Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

5,7 Johnson 200 yard range report #1

#1 Post by Rapidrob » Wed Jan 30, 2019 5:14 pm

I had a chance to go to the range today to try a load from the bench. It was cold but winds were 5 MPH or less. The target was a 1/4 size man torso target set to 200 yards.
My load was a 40 grain Sierra SPFB bullet over 13 grains of IMR-4227.
The 5.7 Johnson cartridge can only take a bullet shape that does not go beyond the nose of a .30 carbine bullet when seated
as it must clear the mouth of the magazine.
The load shoots 6" high at 200 yards so a 6 o'clock hold has to be used. But If I do my part on the rear sight centering the carbine will shoot a decent group.
Here;s the target and I pointing to the group just to give you a reference for the size of the target.
