    18" AR-15 with Hornady 62 FMJ

    Some of you might have seen my previous post where I was experimenting with 60 Vmax. Here is the link if you want more background.

    https://www.m4carbine.net/showthread...ornady-60VMax0

    My setup is an inexpensive AR15 with a KAK Value Line 18" Mid Length 5.56 1/7 twist. It has a Primary Arms 3-9 scope on top and a cheap bi-pod on the free float hand guard. It is kind of a parts bin gun.

    After playing with 60 VMax and a few 69SMK, I decided to try Hornady's 62 FMJ. The one without the steel insert.

    Here is the load data from Hornady.
    https://press.hornady.com/assets/sit...to-60-62gr.pdf

    I loaded up 7 loadings using once fired PMC Brass trimmed to 1.750.
    I used CCI 450 Primers
    4 Loads were H322. 23.3gn, 23.5gn, 23.7gn, and 23.9gns. The last two are over max, but my gun had never shown pressure signs at max with any powder. I guess my camber is large?
    3 Loads were H335. 24.0gns, 24.3 gns, 24.6gns.

    MagnetoSpeed Chrono was used.

    The Targets. Groups are rounded to the nearest 1/4" and measured for extreme spread. I also marked 2 rounds that I knew I threw.


    Normally there is a Vortex 3x Spit-Fire that sits on top of this rifle. I tried a PA 1-6, but didn't like it. It was heavy, eye relief was less than the Spit-Fire and the 6x was not as good as the 9x for shooting at targets. I sold that replaced it with the PA 3-9.

    It looks like H335 gives me what I was looking for. That is a round that can work with the sub tensions for hold over in a Vortex Spitfire when zeroed at 50 yds. I also needed the ammo to use in a urban precision carbine course. It's not a sniper course but I wanted the ammo to shoot sub 1 1/2" MOA and do it cheap. The 62 FMJ is about .11 a round right now. It needs about a .03 primer and .10 of powder. So for .24 cents I can get a decent performing round. The H335 is nice as it makes bulk loading easy with the powder throw.

    I guess I need to load a few more up and confirm it with a few more groupings. H322 also did well, but H335 loads a touch easier and is about 4 dollars cheaper per lb here.

    For those out there looking to push the round....at least in my gun there seems to be significantly more velocity that could be gained if needed.

    I have photos of the casings after being fired that I wanted to add but I keep getting an Error about exceeding my "Quota".

    Ok, I delete some images and was able to upload a few. (They only give you 2mb of space here?). I now how this weird Attached Thumbnails I can't seem to get rid of tho...

    Anyway, here is the image of the casings. H322 on the left, H335 on the right. Charges go up from low to high going Left to Right.

    You ought to try the Hornady 62 gr HPBT W/C bullet. We used to shoot a bunch of the FMJ like you're loading, but the HPBT is damned near Match King performance. Buncha guys here getting sub MOA groups.

    I saw that bullet and will take a look at it the next time a place an order. It looks like it's only available at one supplier? Think that bullet is going to stick around for a while or is it some one off deal? I also think I am going to use the "cheap" FMJ round and easy to load H335 and work my personal shooting skills at this point. I think I have more to do with the lack of consistency in the groupings then the gun or ammunition :-).

    We thought it was a "one off" deal at first, but it seems to be sticking around. It's a GOOD bullet. But on Sunday at 750 yards, we saw where the 77 gr OTM really out shines. 14.5 BCM middy with an ACOG, shot like 1 out of 5 on steel with 62 gr, and I was chasing it around a bit. Loaded 3 77s just to compare, and went 3 for 3 with 2 center flapper hits.

    I'm pretty much in love with that Horn 62gr BTHP. Shot a 5rd group of 1.86" at 200 yards the other day with it, seems like the best value out there right now.

    Nice. Our shooting spot isn't very conducive to groups beyond 100 due to the wind. It's not terrible wind, but it's all over the board.
