I took out my AR 15 carbine yesterday. It has a 1:7" twist barrel and I was using handloads with Reloder 15 and a 75 gr. bthp bullet. I was leaning against a fence post and shooting a steel plate about 8"x10" and getting consistent hits at around 150 yards. It was a cloudy and windy day. My carbine has a Leupold AR 1.5-4x scope with the integral Leupold mount. I was using the 1.5x setting.
