.223/.556 Powder Recommendation

pro2a · May 23, 2020, 07:49 AM

I'm currently using Winchester 748 to load my .223/.556 loads. I'm not having any negative issues but I was just curious what powders others are using for accuracy? Been loading large caliber rifles and handguns for many years but really just got into .223/.556.

Currently all my reloading is for 55 grain bullets.

Same powder i use for that.
Works just fine.
I tried several other powders for the 55gr bullets.
None really outperformed another.

In no particular order, H4895, BL-C(2), H335.

I like Varget.

748 is advertised as burning with a cooler flame temp than H335 (WP844). I bought a pound, but have not tried it yet. I have long noticed that WC844 heats up a sporter barrel on a Savage Axis a lot sooner and hotter than I would like. I found my self keeping several rifles out at the range, to let the Axis cool. Tried ice cubes, too. I now have a heavy fluted barrel that is not nearly as prone to fast heating.
748 will also get you max velocity with Speer 70 graon 224 bullets.

I use w748, BL-C2, and WC846 (when I can find it) for .556/.223, all ball powder, and meter very well, and shoot great.

I have become really fond of benchmark for my 223/556 loads for 55g. I'm shooting 24.8g over a hornady spbt at just under max magazine length of 2.255 for 2927fps in a 16in mid length gas ar, win primers.

Varget is working well for me.

Power Pro Varmint is also showing some promise.

What firearm ?

What do you want out of another powder . Many people have different ideas on what constitutes good or better .

Metering ?

Velocity ?

Temperature stability ?

Burns Cooler then others ?

Accuracy ?

I would think 748 would be a little slow burning for the light 55 grain bullets . My go to 55 grain plinking powder is H-335 . It meters great , accurate enough and gives me good velocities . I do agree that it burns hot it does heat up the barrel and your cases are really hot when they first come out .

Looking for consistent metering.
At least 2500 FPS
Aero Precision Ar-15 16" barrel, so nothing that's gonna get real hot too fast. I do rapid fire quite a bid.
Something I can group pretty decent. I'm not match shooting.

Accurate 2200 is great for light bullets. I have shot 36 grain Varmit Grenades at over 4000 fps. using WP data for 5.56. The bullets stay whole and impact steel plates with a thud at 100 yards.

I like benchmark or h335 for light bullets in 223
