I have a colt 6920 ar 15 with a 1/7 twist rated barrel. What would be the best bullet wgt. for shooting 100 to 300 yrd. | ||

Depends on what you want the bullet to do. Shoot targets, shoot varmints,shoot deer, self defense. | |||

Shoot targets paper and steel. | |||

69 grain Sierra's are perfect for that application. There is no need to go with heavier bullets unless you plan to push past the 300 yard mark. And lighter varmint type bullets will often tear themselves apart when launched from fast twist barrels, so results with them could be unsatisfactory. Yep, the 69 grain Sierra is what you want. | |||

The 69grers would do just fine. I shoot 52gr serria match kings out of my 1/7 bolt gun and shoot very tiny groups. I don't think the 223 will shoot fast enough with bullets over 50 grs to to strip them. | |||

With that twist rate you could just about shot anything that you want out of it and it would stabilize the bullet just fine. I read in some studies that the ideal bullet for the .223/5.56 was a 62g bullet out of a 1/9 twist rifle. But who knows as each rifle is so different. I'm shooting 40g, 50g, 55g, out of my 1/7 AR at some hotter velocities and everything is working out just fine. Experiment and see what bullet your shooter likes the best. | |||

If you are shooting target + don't mind a single load try the Sierra 80 G. .1/6 preferable but I think 1/7 is worth a try.I seem to recall that there was a modifided mag for these extra long ones used @ Perry a few years back.Check w/Glen Zedicher(sp).I just bought a bunch because that is the most perfect loading w/ a 22-250 A./I. 40 deg. w/ 1/6 twist.Virtually little drop @ 600 M. I love velocity. | |||

Ok this reply got me worried. I've not loaded any .223 yet but have amassed a pretty good chuck of materials. Then I read above about single loads. What's the threshold for whether it will be single load or not? What are the factors? I've got a load of 69gr Noslers. | |||

Use 'em. Only a handful of bullets require single loading in an AR. They are little interest to most of us for the obvious reason that they defeat the purpose of a magazine fed, semiautomatic weapon. The Sierra 80 and 90 grain, the Nosler 75 and 80 AMax, and a few others cannot be loaded to an overall length that will function in a magazine and must be single loaded. Just stay away from bullets that aren't loaded in commonly available factory ammo and you'll be fine. Sierra 69 and 77, Hornady 68 and 75 OTM, and Nosler 69 and 77 all work loaded to magazine length.
