233/556 powders.

[BigBronco]

I have been loading off an on for lets just say a long time. I have been using Accurate powder 2230-s 24 gr under a 55gr fmjbt. As I use up what is left of this powder I am going to ask what are your favorite powders for this cartridge? I have been giving thought to Varget since I can use it in 30-06 and 7.5x55 Swiss also. However I am this morning taking a new reloader under my wing and walking him through loading 223 and I would hate to steer him to using my stick in the mud loads. So what are your favorite powders and charge weights for 335/556 loads for a 55g fmjbt? Thanks

P.S. I know about working loads up.

Oh my twist is 1-9 on a 16"

For 55gr, I use 25.0gr H335. For 77gr, I use 24.5gr Varget.

[joelogic]

I use 22.5grs of H322 for my 55s.

I've used most of the common 223 powders and nothing beats Tac IME.

I like WW748 for 55gr and Varget for 69 and 77gr.

26.5gr is a good starting point for WW748 under a 55gr (COAL = 2.235")

24gr is a good starting point for Varget under a 69gr (COAL = 2.250")

23.5gr is a good start point for Varget under a 77gr (COAL = 2.255")

My final worked up loads are 1 grain hotter than the charge weights I recommended for starting.

I have several kegs of 748. Guess what I use.

When I use up my H-335, I'm likely going to try XBR8208 for my .223. It seems to work well in the .223, the 308 Win. and can be used in 30/06 with 150-165 gr. bullets.

Varget is better in the 30/06/ .308 with heavier bullets, but XBR8208 meters better than Varget. XBR8208 is also an ADI powder like Varget is, with a burn rate that fits in the IMR4895 area.

I've been using XBR8208 in the .308 Win. with good results. I will also try it in the .223 Rem., but haven't had the time yet.

To see how it compares with other powders, the Hodgdon reloading site has a very large amount of data to look at. It includes Hodgdon, IMR and winchester powder data and is a very good on line source.

for my blaster/plinking stuff...

55gr FMJ 25gr H335
62GR SS109 25.0gr H335

CCI primers and what ever cases I get my grubby little hands on

[Divernhunter]

Mil brass 27gr of Win748 and 55gr bullet
Comm brass 28grs of same for same

40gr bullet I use win748 or Benchmark

308 and 150-165gr bullets I use Win748.

30-06 with 150-165gr bullets I use Win 760 or IMR4064 BUT you can use Win748

[bootcamp]

55gr. 223rem = 24.5gr of H335
55gr. 223rem = 24.5gr of 2230

Both of those loads will produce decent accuracy with a 1moa/65moa red dot/ring eotech.

Varget... Nuff said...

I've been loading 25.5 grains with 62gr projectiles. You can go as higher, though, according to some loading data....

[GUNNTZ]

H335 or BLC2 have been in my best performing reloads. Both burn clean and give consistent performance.

[coyotebait]

I use reloader 15 for my 55 and 69 grain loads.
