DANG afret!

They shoot good over a lot of different powders. H335 will probably work but you'll be a little shy on velocity.

23.2 8208XBR is a popular load and works great in my AR

CFE 223, CCI 450, 77 Nosler CC, 1:7 18”

Thanks just trying to use powder and primers I have and don’t use far anything else

Only thing about H335 is fill ratio is going to be under 90%

Accurate 2230 or Ramshot TAC are going to be the most available and affordable powder for high velocity in that gun. I don’t know what short barrel means to you but it’s 16 inches to me. My AR’s are 16, 18 and 20. I shoot 62 grain soft points for hogs or anything heavier and those are my AR powders.

This is for my RRA NM A4, 20" stainless barrel:


SIE 77 gr. SMK
LC case
Rem 7.5 BR primer
Aliiant Power Pro Varmint @ 24.2 gr.

Shoots lights out @300 yds., I haven't tried 600 with it yet.

16” bolt gun

77gr TMK
CCI BR4
24.7gr Varget
Starline Brass
2.265" COAL
Used only in Wylde and 5.56 chambers

24 varget and 77smk at 2.6. Shoots in most things I have. That’s what I worked up but reference published load date resources. Start low and work up. I have used 335 but I don’t remember the load Pretty sure I used max published load. Nowadays Tac and varget are what I use. I actually get better all around performance from tac. Meters better and seems to shoot better with better velocity. Plus it’s available and cheaper. Varget gives me better sd’s most of the time.

Those powders will work great. Tac will get a little better velocity before pressure. What chamber? Standard 223 rem? I get 2950 from 24.3 tac but seated long @ 2.565 COL with hornady 80 eld. 2980 with 75 eld. 26 inch barrel.

Standard

You won’t be able to seat them as long as mine but find the lands and back up 0.030-0.050 and go.

The Highpower shooters use 75/77 grains bullets for 200,300 and some even use them for 600 yards. Varget and R15 are very popular as are a host of other appropriate burning rate powders. These "other" powders have grown since the component shortages brought on by covid and anti gunners.The V and R15 loads usually run 23.5-24.5 but need to be worked up for your barrel.

24.1 RL15 load and go. 69, 75, 77, 80..... choose your pill load and go shoot.

 

[RegionRat]

223 - H335 for 77 and 80 SMK data is available on the web and this main site.
The Hodgdon data is for a 24" bolt gun.


This Sierra data is for a 24" barrel.


This data is from Sierra for the AR15 section, this is a 20"bbl.


You will find slightly different velocity depending on your situation.
If you run your development in cool weather, and then shoot in hot weather, you can expect an increase of roughly 100 fps.

Add N140 and H4895 to the list as well, same ranges +2 to work ups.

This is 5.56 NATO data I found in western powder load data manual AA2520---25.0gr. 2.255 OAL with just about any primer. I use cci450 and remington 7-1/2 interchangeably with this load. I e also used WSR and cci400. Accuracy is excellent from my 18" ar15 with average of 2730fps. No pressure signs.
