    +1 on the 55 Vmax. More than a few years ago I had great results from bulk Rem 55 fmj's, both handloads and loaded ammo. Rifle was a 1:8 Armalite Golden Eagle.

    Update FWIW.

    Went to the range ready to throw the whole rifle and scope in the lake! Give it to the Gators! I brought factory ammo from Winchester White Box, PMC Armscor and DRS remanufactured (but they use the Hornady bullet)

    It turns out it is those crummy Winchester bullets. I loaded some of those and some Hornadys with the same brass (LC) and the same Powder AA 2230

    Shot 5 rounds each, several times. Collected brass in between. It started getting hot, feels like summer here so I packed it in after 2 hours.

    The Hornadys grouped at1 to 1-1/2. The Winchesters 2" with some fliers. Tested some factory ammo Win White Box was all over 2+ inches, PMC the same. Armscor did well at 1to 1-1/2.

    The DRS re manufactured ammo which used the Hornady bullet was right in there with 1 to 1- 1/2 groups

    The moral of the story is never change two things at the same time (bullets and powder) I saved enough ammo to test again in another rifle to verify.

    I did not adjust the scope at all and just let them group were they would. Shooting at the Caldwell Orange Peel 4" targets 4 targets to a sheet. Just trying to keep them in that 4" circle.

    I repeated the Hornady VS Winchester bullets several times and with several powder charges. The Hornady did better every time.

    Next trip I am bring the longer barrel bolt action any maybe I can better results from that rifle to use up the Winchesters.

    1.5-2" at 100yds is about what you should expect out of that rifle.

    Glad you were able to sort things out

    Thanks. It was much better today. but I am not sure it's totally "sorted" out

    I shot a few Federal Mill Soec 62 gr ammo and was not real happy with that but that may be just a scope adjustment as it was high and got mixed in with another group.

    Guess this is why I prefer handguns:D

    If you want better groups, buy better bullets. Period. ;)

    Lemme rephrase that.


    What kind of accuracy do you need with a 55 gr in a stock AR15??



    4" is still all kinds of dead- but I know you can do better than that.

    Have you checked the nut behind the grip, too ?

    ITs alignment can really shape up your groups quite a bit.

    Not all guns are born "shooters". But if thats all you had, a heavier bullet would probably shave an inch with the above advice, and a little lane time.

    There is only so much dead. Not every rifle is a snipomatic 3000. A stock AR shooting 55 gr pills is not the first thing that comes to mind, either.

    When these 2,000 are gone I will:D If I was shooting a steel gong, these would be just fine. As I mentioned, these bullets shoot fine in my Savage M 12 VLP DPM

    I have match grade bullets for my 308 bolt action, but it also has a match trigger, match stock and optics that cost 3 times the rifle.;)

    Seems you are getting a lot of good advice. I don't shoot FMJ's it is a waste of good powder. I use Hornady's 55 SP for plinking and varmint control. Barnes TSX for killing bigger stuff. I can get 1"-1 1/2" groups out of my Mini 14 with the barnes 62 grain. Yes out of a mini. Nobody at my club could believe it , until they saw it for their selves.

    YMMV. Scoped AR, built from components. 16" Heavy Barrel Del-Ton upper. Handloads. 10 rounds from sandbags, 100 yards. I have 3 of these homebuilts, and they all do this kind of work.

    When I want to check variables I use Hornady V-max's as my base line bullet. They have never failed to be accurate for me. I can't say the same for bulk FMJ's. kwg

    4 inch groups at 50 aren't very good.Might try some different loads,especially bullets.My AR is never over 2 MOA with 55's and with 69 gr Noslers it usually is under 1 MOA.Sounds like something going on with the rifle.
