Steel at 600YDS with a .223
- Thread starter Hal
- Start date
69gr Sierra MatchKings will do
70gr Bergers.
Try the 75gr Hornady HPBT Match, but they might be borderline instable.
I've heard the 75gr AMax shoots ok out of some 1:9s, but you need to single load it anyway as cartridge OAL will be more than mag-length (very long bullet).
68Gr Hornady Match will do too.
600Y will be tricky to shoot with the wind and the light bullets, but don't be tempted to try 77grs, or more. Even the 75grs are pushing it.
Without knowing your barrel length, the 68/69s like ~2900 fps from my 20" AR barrel.
Powders: Varget, CFE223, AR-Comp, BLC(2), IMR-4895, H335, H322, and many more. Check Hodgdon's website for loading data and where to start. VVN133/N135/N140 work well too. Ramshot TAC and IMR-4064 will work.

PS: I shoot 600y often with my .223 AR, and it is very fun. I cheat and use heavier bullets, but the 69gr will do just fine. Get lots of practice reading the wind. To do grouping at distance without so much wind effect try 300-350y for load testing.

My 1in 9 LOVES 77 SMK........shot some decent FT/R scores at 600.
The problem with steel at the range, you may or may not hear the impact. I have sometimes saw the steel move, but depending on wind, not heard the impact.

Ps, it is my experience for whatever reason, the 77 smks stabilize easier than the 75 amax. My rifle does not like the 75 amax...(24" kriegered AR)

Ok, I stand corrected. Most 1:9s that I've heard of haven't had a developed 77gr load, or something like that. Try it with caution, but CERTAINLY the 69/68s or Berger 70VLDs will behave very well.
At 600y, the steel is a bit quiet, at 760y, it sounds like a pin drop
In both cases you should see the shock impact, but a hanging or otherwise target with some motion helps too. We like to give a fresh coat of Orange or White paint, then you can see the impacts.

remember that twist is about bullet LENGTH, not weight...
a horn 75 amax has a light weight tip which significantly adds to LENGTH...
try the 75 match and the sie 77......
i would pass on 68/69 for 600 unless i could not find anything else that worked....

Mine shoots the NCC 77 good.
Its the 700 Rem Tac...9 twist.

The 53g Vmax shoots better than the 69g MatchKings out to 600 yards in my 9 twist .223. Not by much though. I shoot them on top of 25.8g of Benchmark and they shoot extremely flat and accurate. Its a hot load so SLOWELY work up. I havent tried the 77g MatchKings, but I would definitely give them a try if you are gonna shoot in 600 yard matches. Good luck.

can you explain how you do this ??
i get 106% of case capacity using 30 as a vol
62+kpsi pressure..what do your primers look like ?
what gun how long of a bbl ??
50 53 or 55 vmax ???

53 grain bullet and 26 grains of benchmark as max load on the Hodgens website. Yes I know its not the same exact bullet. The rifle has a 26 inch barrel and it has a very deep throat so the COAL is 2.34" just touching the lands. I been reloading the same Lapue brass many times with this exact load and my primer pockets are fine. Zero signs of pressure.
ar10ar15man
do you realize that you posted a load that is probably unsafe in most guns ?/
do you realize that 2.34 is a MERE 090 LONGER THAN STD ///
THAT WITHOUT MENTIONING THE OAL YOU LEAVE OTHERS OPEN TO DANGER ??
CRAP...

Did you not see where I put SLOWELY work up in BRIGHT RED LETTERS?????? Maybe some rifles wont shoot this load, but thats why I put SLOWELY work up. I have read several of your post the past 2 months and all you do is attack what others do and how they do it. You sure like to point out what other do and how they do it wrong and you can do it better. I have seen several topics the past 2 months where you attack my fellow forum members and pissed them off. You should just leave this forum and dont come back. Dont respond back because I truly dont give a crap about your BS

NO WHAT I SAID WAS THE ENTIRE INDUSTRY USES CORNCOB( well that part that does not use liquid)....
i have been in the field for 6 yrs....but i have been using corncob for over 20......
and i doubt that you have been shooting since i was in diapers....
is that 47 a clue ?? as in 1947 ??you would be one yr older than me...
and both of you pick on me instead of addressing the issue...
POSTING POOR LOAD DATA...
he says no pressure issues...but fails to note his load is .090 longer than std.
he says 53 hornady..but then admits he is using a different bullet than the load data at hogdon....

Nomad47 said:Stinnett, its a sure thing that he never took the Dale Carnegie course.
He told me that walnut media was no good and I must use corn cob. I would venture to say I've been shooting since before he was in diapers. And he has been selling brass for 6 WHOLE years so he must know it all.

stin,
i may owe you an apology.
my version of quickload shows 223 rem case volume as 28.8.....i am being told the current default volume is now listed as 30.8...that is a big difference and would drop the pressure a bunch.
i believe the 30.8 is way to big but that is just me. i just did a sampling of two different federal lots of 223 rem brass and got 30.3....closer to the 30 i had used...
so there we go....
if people would list all the criteria of a load, these discussions might be much shorter...esp for top end loads.

I have seen multiple 1 in 9 barrels that LOVE the Sierra 69gr MK. I personally witnessed one high-power shooter score a perfect 200 at 500 yards with Varget and a stock bushmaster barrel in 1 in 9. High x-count to boot.

Likewise, it is the bullet I'd recommend for anyone with a 1:9 looking to go farther. I've read quite a few stories of some barrels liking 75, 77 and even 80gr, but I'll leave those to the OP to test individually.
My 1:7 is just as picky in the 70-80gr range, and likes the opposite of what I'd expect.
