OK so I built up a varmint gun and its great for all the ranges that are local can really stretch it out much around here. I was wondering how far I should be able to get out of it, what range I could hit steel, what range I could group at and what range the bullet would hit paper but if it was an actual threat or animal would the bullet fragment correctly or effective range. All ammo will be match grade or reloaded

specs on gun:
-stag lower
-m1s upper and hard chromed bull barrel 1-9 twist 24 inches
-free float hand guard
-prs stock

That 45-65 grain bullet is going to be greatly affected by cross winds especially at great distances. The military practices out to 500 meters (I believe) with their M-16s. Would not want to be shot at any range with the "poodle shooter" rounds. The BC is not very good on them. My son says that the 284 is the round I should be using because of it's extremely high Ballistic Co.
ETA: nice looking shooter you have set up.

You should be able to get hits well out to 600yds especially with 69gr SMK's, however there are better options in terms of effectiveness when you get out past 400-500yds. Going with a 1:7 or 1:8 barrel would allow you to step up to 75+gr bullets which would extend your range.

Blame any misspellings on Tapatalk

You need the 1:7 twist to shoot the higher grain stuff and be less effected by wind. I have seen people take it out to a 1000 on occasion, but that's not practical with .223 vs varmints, out to 600 is practical.

Now if you want to talk Varmint AR's at 1000 I know some guys with AR's chambered for .260 and 6.5 credemore, they are nasty! I imagine 243 would be nice also.

As far as military the Army qualifies out to 300m only or did when I was in, the Marines take it out further. Army Infantry sometimes practices out further than 300. The army primary uses the short barreled M-4, Marines use the M-16.

Being a varmint gun, for hunting varmints at long range, it fits hunting also :D

It is still a military inspired weapon.

LOL Yes but the intended use and question is related to long range hunting, thus the question might reach more experianced varmit hunters, in the hunting section. :D. Let me know when the military starts setting up varmit AR's

I think I will go post a deer hunting 308 ar in the hunting section just to bother you and be a pita lol :D. Joking

We also post .22 ars in the military section.
The military does not use .22 to my knowledge.

I wont argue about it and I wont say its a rule, rather an unspoken one and a polite reminder to folks to keep threads in right area as its helpful to others. I never come in this section other than to move threads to their right section which I am done doing.

Post where you like. But it will get far more traffic in the right section.

Guys,

Play nice.

With 52-53grn match you are good to 40yds / 450yds until the wind drift becomes a issue.

Since it is a 1/9 twist, you need to shoot some 68, 69 and 77grn in that rifle. If any of these can group .75 MOA @ 200yds you will be good to 700yds.

Shooting out on range 66D on base we pushed a bolt action 223 out to 800m and the weapon hit well. Keep in mind this was done with handloads. We also push a AR 223 out to this distance and it held MOA as well. So the rifle will take the bullet out there. But those were some really tuned rifles.
Most Mil rifles will shoot out to 600m with Iron sights and hit a man size target. It is the shooter that messes it up. There are not many areas in NC where you can make a shot of more than 300m. So you should be good to go as far as hunting.

I shoot NRA/CMP service rifle and shooting at 600yd is part of the course of fire. Granted, I am shooting handloads using a Berger 82gr bullet in a 1-7 twist barrel. I've also shot my A2 service rifle to 800yds using iron sights and managed to hold the 9-ring (roughly about 30")

As stated, the twist rate on your barrel is going to be the limiting factor. A 69gr bullet will certainly reach to 600yds, and perhaps a little farther, but you will be losing a lot to the wind. If you play around with load development you might find a good bullet/powder combination.
