What's your most accurate 223, 50grn load?

What is your most accurate 223, 50grn load? I'm hoping to find a super accurate load in the upper velocity nodes.

26.0 grains H335 with Nosler 50 ballistic tip. Not my fastest load but my best for accuracy.

 

[MtheN]

27.0 grains of 748 with 50 gr TNT's loaded to mag length. Shoots low .3's in 1/12 AR.

25.5 BENCHMARK is outstanding-good velocity and 1/4" groups.

25.5-ish gn of H335 or 26.5-ish gn of W748 behind a 52-53gn bullet have long been 'golden' in a lot of .223 Rem... little more powder with a 50, little less with a 55... which agrees pretty closely with some of the above loads.

 

[SS427]

All my .223s shot best with N133 powder. (I've only owned 3 though.) I tried Varget, IMR3031, H4895, H335, Benchmark and H322. Nothing worked like the N133 though.

What is your barrel length and twist rate?

 

[AckleymanII]

Matt, here you go, 3600 with 50g in 223, 14 twist

26.0g of N133
Rem 7 1/2 or BR-4
Use Lapua brass, you need tough or back off to 25.5g on NEW Lake City brass
Seat the 50g Nosler ballistic tip, 50g Speer TNT to touch the lands

N133 re writes the book on speed with super accuracy with the 50g, for the 55g, use N135

Actually, i have a pound of N133 I've had for about 8 years and never used. I'll load a few up and try it! I'm using Winchester brass btw. Also, my barrel is a 1-9 twist.

Thanks!
Matt

27.5g w748, 50g vmax, 3232fps in the ER shaw 24", 1/14" tw bbl., averages .400" @ 100 yds.

I SHOT 25.5 GRS V-133 50GR V-MAXS 450 PRIMERS DID A GREAT JOB FOR ME IN A SAVAGE TACTICAL 24'' 1/9

26.2 grains of H-335 with moly plated 50 grain Ballistic Tips at 3335 in a 22" 700 varmint barrel.

 

[ranger3]

25.5 gr. Benchmark, also works with 53 gr. Vmax 7 1/2 primers. Great out to 300 yds, furtherst I've shot it 9 twist.

 

[long40shot]

I've found the node my rifle likes is between 25.4 - 25.6 of Benchmark.

 

[K22]

I've tried Varget, H4895, Benchmark, and H335. All shot extremely well with all my 12" twist bolt rifles with 50 AND 55 grain Nolser BT's, Sierra 50 grain Blitz, and Hornady 55 Vmax. All with Federal 205M primers.

I'm currently using H4895 in all my 223 bolt rifles both with 50 and 55 grain bullets. It gives me the most consistent, accuracy, temperature stability / lot to lot results in all my rifles. My current bullets of choice are 50 and 55 Nosler BT's. I shoot the 50's out of my shorter barrel stalker rifles and the 55's out of my 26" heavy varmint rifles.

 

[chkunz]

The Sierra manual lists the accuracy load for the 52 and 53 SMK bullets as 23.5 grains of N133. I tried this load in my AR 20 inch WOA barrel with 1 in 8 twist and it does well. I am using this load for the NRA 100 yard reduced course high power rifle competition.

In my 40 plus years of shooting, I've learned a couple of things; one basic one is that each any every firearm is self specific as to what it likes in terms of ballistics. In short, every rifle has its own specific choice of cartridge. Two seemingly identicle firearms will have completely different preferences in terms of bullets, powder and charges.

N133 may be part of the perfect recipe for your rifle while mine loves H4350. You can't even begin to decide what going to work for you and your 6br just because mine happens to have a preference for it.

All you have to do is look at the prior dozen posts and appreciate 12 completely different recipes to understand what I'm getting at.

 

[SSL]

.250-.330" 5 shot groups when I do my part with 24.0 grains of original AA DATA2200 under a 52 grain Hornady HPBT Match at 3420 fps from my Ruger #1B with 26" barrel. Same load works almost as well with 50 grain VMAX. While this has been a safe load for me for years, it is a maximum load and should be worked up carefully.

N133 may be part of the perfect recipe for your rifle while mine loves H4350.

I'm betting against H4350 with a 50 grain bullet in .223.

Between 21-22 Grains of IMR4198 or H4198 work up to 22
