    I'm looking for advice on which ammo to try in my AR. It has a 16" 1:7 chrome lined barrel. The previous owner put 60rds through it and told me it likes 62grain ammo, but with only 60rds downrange...... :confused:

    I know the 1:7 is for heavier loads, but what is considered heavy, 62gr 69gr?? :confused:

    I'll be shooting from 50-100yards. 100yards is the max range where I shoot until I go out to the woods. :)

    Another question. Where do you buy bulk ammo online?

    I believe 1:7 would take amost all type of ammo weight but preferred heavier load like 62+. Or I would hope so because I won't be able to afford 69gr + ammo all the time lol. 55gr and 62gr are affordable with Federal and PMC.

    Generally speaking anything 55gr and up should be ok. The shorter barrel may allow you to go lighter with some of the so-called ballistic tip varmint rounds but I personally see little benefit to the added cost.

    62gr green tip ammo seems to be readily available at good prices and that gun should be damn near perfect for 'em

    Good luck and have fun with your new SUR.

    Any damn thing you want to shoot. It's a chrome barrel! 55 grain and up should do splendad at the yardage you are referring too. ;)

    Ok, thanks for the tips. I'm going to try a few different ones and see how it goes.
    Wish I had a longer range to shoot at.

    50-100 is plenty for a rifle like that. The way I look at it is the longer the shot the more negatively the jury will look at it.

    Yes the 1:7 will shoot 55gr bullets just fine. However as a rule the 1:7 normally likes the range for peak accuracy of 69 grain. But will even handle in the 70+ very well also. But at 50-110 the 55s will shoot decent also.

    Got the best results with black hills 62 gr green tip.
    One things for sure. This is FUN!!
    I zeroed in at 25 yards, then moved out to 100. The Tula is some dirty crap!!

    Glad you had a good time. I took my new one out today too. I used 55 gr Federal and PMC Bronze with no problems
