You MIGHT get there with the .223, and maybe some 30s or 35s, but I doubt you'd find the accuracy needed with those shorter, light bullets.
If you desperately need 4000fps, you're in need of a bigger case, like the .22/250. Then you can use the useful 40 grain weight, and not crowd high pressures, and hit your goal of 4000fps. The .22/250 can do 4000 easily, and can crowd 4300 with a caseful of Varget. I just don't think you can do 4000 safely within SAAMI specs, with a standard .223.
You can roll a turd in peanuts, dip it in chocolate, and it still ain't no damn Baby Ruth.

3800fps with 40s with 26g Benchmark in FILs 26 inch Model 700. My 223AI barely makes 3800fps with moly'd 40's and 29.1gr of Benchmark...Didn't think 4" of barrel length would make that much of a difference.
Why pack all that messy meat out of the bush when we can just go to the grocery store where meat is made? Hell,if they sold antlers I would save so much money I could afford to go Dolphin fishing. Maybe even a baby seal safari.

Ain't gonna happen with a 40 grain bullet. you can get upwards of 3800.

I have a 223 with a 26" Hart with a Minimum SASMI spec chamber that will put all the bullets in the same hole at 4000 fps with the 40g Nosler.
I use IMI or Lapua brass 7 1/2 or BR-4 Primers Vit N-133 powder.
My 26" 223 AI will shoot the 40g Noslers at 4200 with N-133, formed IMI brass and 7 1/2 primers.
N-133, Tough brass, and thick cup primers are the key, the minimum spec chamber with Zero freebore may help seal the gasses behind the bullet.
With N-133, I shoot the 50g Noslers at 3800-3850 fps into extremely tiny groups in the 223 AI....no brass issues yet.

I'd say you can get it there with the powder you are using, but not without exceeding SAAMI specs for the cartridge.
May I ask why 3,800 is not enough?

GS Custom HV 40g bullets with 28.5g (not 26g-misspoke earlier) of Benchmark shoots 3800 fps (3815 to be exact) in my FIL's 700SPS.
Your results may vary.

I have found 3800 to be the practical limit for 40 grain VMax.
That said, as stated above, some extreme measures may get you a little further. Whether you are going into an accuracy node or leaving one is another thing.
The best load I found was with Accurate Data 2200, sadly no longer available.

Your results may vary. Think you can look, look, and look and at the most you will find 27.3 grains of Benchmark to be max you can find for the 40 grain bullet. If you decided to work up to that much powder be very careful. I get a snug bolt with 27grains in the summer so I have chosen 26.5 at a little over 3600fps. Newest Hornady manual only gives 26.4 for a max load.

H335 might get you close to 3900 fps but you may need to use a 2 part epoxy to hold your primers in! whelennut
I like to do my hunting BEFORE I pull the trigger! There is only one kind of dead, but there are many different kinds of wounded.

Why on earth do you feel you need to get 4000 from a 223 and a 40 grain bullet?

Newest Hornady manual only gives 26.4 for a max load. The driving bands on the GS Custom bullets allow you to load to higher velocities. On their website, they have 3800fps as the velocity to load for with that bullet/powder combo. Start less and work up applies to everything reloading. Simply stating that 3800fps is obtainable with 40g bullets in the .223.

I have a 40X rebarrled by Hart Barrels with a 27" 1x14 twist barrel. I use IMI brass, CCI-450 primers, mollied 40 Nosler's and a good helping of WC-844 pull down powder. This breaks 4,000 FPS over my Oehler 35P at 10 ft.

Toms22: I have a couple of 223's that are shooting 40 grain Nosler Ballistic Tips and one of them I have checked on my Oehler chronograph at 3,363 F.P.S.! I have shot this load for years now and I am very pleased with it. I would not even consider trying to crank those bullets from that Rifle (with its 25" Shilen barrel!) up to 4,000 F.P.S.! The loading I am running in that 223 is extremely accurate and VERY lethal on all manner of Varmints. I checked a couple of sources and safe maximum loads with 40 grain bullets seem to "top out" at 3,600 to 3,800 F.P.S.? Yes faster means flatter and straighter but there is a limit (mandated by safety!), and 4,000 F.P.S. is a bit beyond the limit. Best of luck with your 223. Hold into the wind VarmintGuy

I'm with VG on this one. Say I have a couple of friends with .223 AI's they get just under 4K with 40's. If you really want to go there with a .223 get a .223 WSSM.
