I was playing with my 223 to day and i used reloader 15 at 7gr and a 55 gr hornady.On my range here at home is only 70 yards but i got a five shot group under 1/4 i have know idea what the f.p.s. is but it hit the backstop pretty hard.If any one has an idea what the f.p.s. is i would like to know.The gun is a savage bullbarrel 24''.Thanks guys.

I don't know about...out to 70 yards but, I have two loads for about 1850 [estimated] FPS.
[55 grain bullet.]
7.3 grains of IMR 4227
5.6 grains of UNIQUE
Both shoot 1/4 inch at 25 yards.
