I have two 7.62x39mm rifles, and both are accurate enough for me.
My CZ 527M is a great little bolt action carbine, best camp/hiking rifle I have, very light weight, and very easy to use. As I have stated here before, according to the Internet I am a terrible shot.
This one likes that Berry's plated bullet, 125 grain puppy.
Still working up a good cast load, working on hardening up the metal.
My other is my SA vz-58.
Honestly, this rifle is just plain fun to shoot. It isn't as accurate as the 527M, but I can hit minute of bad guy at 200 yards.
Just for fun, I did this farting around the other day, Range is subminiature, 25 yards, shots taken standing, targets 1.5 inches wide, 2 inches tall. I got 4 out of 6.
I know everyone else here can do better, but I'm OK with this. The rifle is fantastic, full pound lighter than any AKM clone, and that with a milled receiver.
I will say I had the steel target out at 300 yards some time ago, and with a buddy watching, scored 4 out of 6 with the vz-58, 12x8' 1/2 scale IDPA gong. Also hit it most of the time with the 527M, iron sights at 300 yards. It was a VERY good day.
