5.7 at 300 meters

[Rapidrob 0]

I was trying out a new load for my 5.7 carbine and found I had a quantity of 40 grain FMJ bullets. No idea who made them or for what original cartridge. It was very windy at the range and I only set up out to 300 meters as the 40 MPH constant wind was going to play havoc with the bullet flight.

As it turned out the wind was a "Range Wind" and the little 40 grain bullet was able to hit the 24x24" AR550 target most of the time. It still had enough oomph to leave a nice dent on the surface of the target.

I was going to move over to the 500 meter target but the wind was getting worse as the day progressed.

During the early 1960's, Dad and his right-hand man, Jack Fitzgerald, used .223 Speer 40 grain FMJ bullets, and Sisk 40 grain soft-points. Later, after Dad passed away in 1965, I ended up with Winchester .2235 40 grain FMJ bullets. At that time, we used 11 grains of #4227 powder and produced MV of 2800 and 720 foot pounds of energy.    ej
