77 or 80 grain bullets in a fast twist .223 will get you to 600 yards. Nothing but a .22 LR would be less expensive for practice.
+1.
This super-cheap PSA AR is one of my more fun rifles (18" SS 223Wylde 1-8" barrel). It was a bit breezy Saturday morning so I did some 400yd shooting with 77's to see what kind of drift I'd get, and to check dope on a newly swapped scope. I only learn so much when I just shoot on the calm/still days. As much as I like bolt guns, I would have never thought I'd be grabbing an AR first thing to go do chores or stop by the range.
Very nice Jpro. I feel the same way about the 223 rem and AR's.. A lot of great advice here. I will generally take one of my AR's out when I go to the range as well. I shoot a lot at 400 yards and run a lot of 69gr sierra's. I'd step up to a 77, or not, if practicing out to 600-1000 yards. At 400 the 69 is pretty impressive. Great for practicing in the wind:
I'll shoot 3 shots to check POI when it is windy. I was holding 2 moa off on the last target and the wind still caught those bullets.. One thing that needs to be said. It's not always about the bullet. Here's a fast twist Tikka 22-250 I was shooting a couple weeks ago. Using 77 SMK's:
The group size is horrendous, but my hold over to the left was spot on for the wind call. Now, here's another Tikka 22-250 with a 1 in 14" twist barrel. The rifle is a little heavier, since it is the varmint model. It shoots 53gr v-max like nobody's business:
That rifle and bullet will continually outshoot my CTR's chambered in 6.5 creedmoor.
