Am I wasting my time mounting a 9x scope for 600 yard shots? I solved the drop with a special reticle and I had thought to put together a poorman's sniper rifle, but perhaps I should start over with a 223 bolt gun reserving the Woo for under 200.

that's probably a stretch for a battle rifle.

^ Yeah, while you "can" make hits at that distance, the 5.56/223 doesn't have much punch left. Better off with a .30 cal or bigger, IMHO.

Bullcrap. If it has a 1 in 7 twist, the 77 grainers have plenty of punch left at 600. I could never come close to achieving the scores I shot with a NM AR with 1 in 8 twist at 600 yards with a NM M1A shooting 175 Sierras. The 1 in 12 will be a different story, the 55 grainers are about maxed out at 600.

A 77 shot at 2850 feet/sec will still be doing over 1400 feet/sec at 600 with about 340 foot pounds of energy. A 55 FMJBT shot at 3300 feet/sec will be under the speed of sound with about 1010 feet/sec and 125 foot/lbs of energy. A 150 grain FMJBT Sierra starting out at 2700 will be doing about 1400 feet/sec with 650 foot/lbs of energy.

I have read that the 77 grainers have been used at 1000. But since my Woo is 1 in 12 and using a 55 grain bullet can I hit anything at 600? Intrinsic accuracy with a decent shooter, of course. Lethal effect should be another thread.

We're talking Daewoos here Hagar, not "National Match" AR's, let alone NM M1A's. How many Daewoos have a 1/7 barrel? If that 77gr bullet is so awesome, why do we cling to 7.62x51?

I shot a plain Jane A2 AR15 with 1 in 9 twist at 600 using 69 Sierras (when I could still afford to buy them:sad:), and shot a pretty good score. A Woo with 1 in 7 twist should not be much worse.

We did have an idiot once that was shooting his varmint bullets at 600, and they were bouncing off the frames and into the pitts. If I was the puller or the pit boss, I would have DQ'd him right away.

Who is clinging to 7,62? Maybe only the Marine snipers, and they prefer a 300 mag or bigger anyway. The AMU team long ago gave up on it, even for 1000 yards.

Nevermind, hagar, I'll just let it go.

All I have to work with is the scope. The rifle I would pick to shoot at 600 is not at issue unless I buy a bolt.gun. 55 grains (maybe 62?), 1 in 12 twist from a stock Woo DR 200. Thumb hole stock actually comes in handy for once.

Your best chance of getting to 600 with that twist is the 60 grain Sierra, at 300 (furthest I have shot it), I have yet to find another bullet that could beat it in a no wind situation.

300 yards? That is helpful. What kind of groups at that distance?
