Thread: .223 Hornady ammo question

    .223 Hornady ammo question

    Hi Guys

    another question for the world of Stalking Directory

    Does any one know what black spherical powder Hornady use in their factory 55gr .223 ammo, my mates tikka only groups well with the Hornady factory ammo and were trying to do a bit of load development using other sized bullets and we'd like to use the same powder, he's tried using 90gr bullets though the rifle but they seem to be going side ways

    any info would be much appreciated


    regards

    Unlikely to be a straight replica of a powder available on the retail market unfortunately

    i spent a while replicating Norma 130gr sp rounds using n160.
    doubt it will be identical but does the trick!

    try a variety of powders in the n130/133, h322, rl7 range

    Hi,

    If that's a tikka 595 then its not the powder. A lot of them including mine have the wrong twist ( too slow or too fast - cannot remember) to stabilise much over 60gr bullets. The rounds end up going all over the place.

    Try H-322 or H-335 powders and yes, use the proper bullet. The only reason a person would shoot 90 grain bullets in a standard .223 is because he didn't know better. Maybe it's his loading that is causing the problem with lighter bullets? The powder is the least of his problems. Tell him to look hard at the Hornady round and, powder aside, try to replicate it. Full Length resize. Trim to uniform length. Load with an appropriate charge of appropriate powder, seat carefully to recommended OAL and crimp with a Lee Factory Crimp Die. That will get him as close to factory ammo as he can get.

    I find it amazing that people sometimes try to duplicate a kick-a$$ factory load by neck sizing, seating the bullet to .010" off the rifling....and doing everything the factory doesn't do while fretting over what powder is used in the factory offering.~Muir

    thanks for the info

    think my mates ok with the principles of reloading as he reloads his .308 Barnard action to shoot 1000yrds at diggle more often than not he finishes in the top three or four every fortnight, along with his .338 lapua magnum which he won the fly shoot at diggle the other week so his reloading skills aren't the problem, the problem he's been having is that He bought this Tikka T3 Tac in .223 some months back but grouping have been not good to say the least this rifle was supposed to have a 1 in 8 twist barrel so he could shoot the heavier bullets but looks like he's been sold a 1 in 12 as it doesn't like 90 gr bullets but does seem to like some of the 55 gr, we chrono'd all the shots which were all around the 2900 fps to 3200 fps but the 90 gr bullets were doing an average of 2300 fps but flattening the primers which was worrying

    it is still picky even on 55gr bullets we tried Remington 55 grain factory ammo then Seller and Belliot soft point 55gr next came the Federal American Eagle 55gr without much success and lastly we tried the Hornady 55 gr factory "Practice" steel cases ammo which gave good tight groups, this is why i am asking the question regarding the powder, we were hoping to replicate the load with 55 gr heads and a similar type powder to the factory ammo


    many thanks

    Not to pee on your buddy's pant cuffs, but shooting and reloading are different. I don't know what kind 90 grain bullets he was using but the Sierra Match King's, for instance, require a 1: 6.5" twist to stabilize and at best IIRC and that Tikka is a 1-8" twist so he was headed for failure there from the start.

    I don't know how your friend loaded the ammo he tested but I can tell you that the steel cased ammo usually has a huge amount of neck tension. Were I he, I would do as I advised earlier: FL resize, seat to recommended spec and crimp. H322 or H335 will work well.~Muir

    I've tried all sorts of powders in my 223, TAC,Xterminator,H335, N133 and benchmark. All produce great results if the bullet weight is right. Mine likes 52gr amax- 60gr v max. 223 is a great round to load for and not fussy about powders. Lack of bullet stability more likely as discussed due to rifle than powder IMHO

    90g in a 223 is a very specialist bullet with a very specialised rifle and loading processes.

    id stick to around 40-60 g unless your rifle has a 1-9 or 1-8 twist barrel in which case you can go up to 69g in 1-9 or 75/77/80g in a 1-8 ?

    it sounds like your trying to make the 223 something it isn't ?
    Right where's those stones , I'll start !

    Lee, Max bullet weight in my .223, (cut Border barrel), throated & twisted (1:8)for the bullet in question is 69 grain.

    Won the fly shoot did he ? What class ?

    90gr in .223 ? Why ? That's pretty specialised, requiring a seriously fast twist, and as far as I'm aware, the only 'factory' gun with tight enough (possibly) twist rates are the NEA15's at 1-7" but that's debatable.

    55's in a 1-8" can be fussy as it's almost too fast, in a 1-8" you should be looking at the 69 gr smk's or similar.

    The tikka will say on the barrel if it's a 1-8" twist, and yes, they will run the 'heavier' bullets, but not the 'heaviest' ones.
