I would go with IMR 3031.

I like to think of it as an all purpose .223 powder.

I use it in match loads and I get really good results.

Hodgdon 322 or Vihta Vuori N133.

When it becomes more available, IMR 8208 XBR is gonna rock.

Is this a new powder?
I haven't seen or heard of it before.

The above suggestions are good, I'd like to add AA2230 to the list. It meters like water out of my 550, gives excellent velocity, and its been ultra accurate out of my varmint AR.

Well, it's a new formulation of an old powder, and is intimately tied to the early years of the AR and interestingly, the sport of BR shooting.

For the AR, it's got the ideal burn rate for the system. IMR 8208/T-32 is what was originally spec'd for the ammunition.
For BR, it is the most insensitive and stable powder. EVER. You develop a load with old 8208, and that load works anywhere you take it.

IMR has been tweaking the powder for the last couple of years, and it's only hit the market this month.

I will have to keep my eye out for it then.

I am always willing to try new load types.

Pick any two from your list except substitute 2230 for the 2015 and Reloder 15 for the Varget.

I think you should try a ball powder and an extruded powder. TAC or H335 and RL-15 or H4895 are solid choices. H322 is a little more suitable for slightly lighter bullets, but will work pretty well. Varget has grains a little larger than RL-15.

There are no bad choices in your list.

I wonder if they'll put the thunderbird on the label - that will make it sell by the train car load around here.

The labels I've seen are just standard IMR labels. Accurate Shooter had a blurb about it a couple weeks ago with some pictures.

H335 is considered a go to powder for 55 gr bullets in the 223,Meters excellent from most powder measures,has a
wide range of powder weights
Some consider 25 gr of H335 and 55 gr bullets a standard in 223,expecially in AR's
Work up slow using start loads from manuals and powder company recomendations.
Win 748 is also excellent

What 55gr sp? If its a Sierra, you won't have much trouble getting it to shoot. I like 21.5gr Reloder 7 with the Hornady 55gr SP and pretty much every other 52 to 55gr bullet I've tried. With Noslers TAC is very good.

Just about any powder will work with that bullet. Here's some Data 2200 goodness from a few years ago. 10 shots, 100 yards. I like Varget and Data 2230-C also.

My favorite go to load is also 25.0 gr H-335 with 55grain V-Max bullets. H-335 meters so well thru my Redding BR-3. I weigh every 10th charge, but they never vary more than .1.

I want to experiment with AA2230 when I get a little time to work up loads for my RRA 8:1 fast twist barrell and heavy bullets.

Tac because its the cheapest and most versatile and you really don't need the nth degree of accuracy a different powder will give you from a battle gun.

Maybe my question should change. What powders should I not get?

This was exactly the answer I was going to use, so +1.

Simple, buy a pound of anything they have in stock that is on your list.
Our cabella's has zlilch for powder.

8lb of what is on sale or available these days is what works best.

All guns and shooters are different.

Tried many and really can't tell a difference. But if you have a
cheap plastic powder drop measure then ball powder will work
best cause some of those stick powders jam the cheap plastic
crap up.

I have used TAC, Varget both with great success.

My go to powder now for 55gr in the 223/5.56 is TAC since it meters very consistently and I have not had the issues with my powder drop that I had with Varget and the small mouth on the 223/5.56 case. Varget's extruded grains seemed to hang up on occasion feeding into the case mouth when using my powder dispenser which in turn made a mess and wasted the powder. Not an issue if your charging by hand.

Don't get me wrong Varget is an outstanding powder and I use it for my 22-250 where I hand measure every charge and in 308 and 30-'06 using the powder drop. The larger case mouth of the .30's seems to be more forgiving with the Varget.

I have used H322 & 2015 with great success. Also here good things about Varget & 2230

I haven't seen anybody say anything about H4895. This is the powder I was going to try first, mainly because it's velocity/pressure ratio looked pretty good and it's supposedly pretty much the standard MIl-Spec powder, along with IMR 4895. What's the downside to these powders?

I use Benchmark exclusively for 55-60gr bullets, it meters very well and shoots amazing were H-335 was 2-3" groups at any given load charge in my rifle.
ziarifleman  [Team Member]

4895 (either H or IMR) is a good powder for the .223 all around.

I personally prefer something a little faster for exclusively light bullets, but there is nothing wrong with 4895.

It will give better case fill than a lot of the others, especially the ball powders.

If your taking a poll

1. Benchmark
2. Varget

I'm not finding any Reloader 15 load data for a 55grain Hornady VMax

My 2 favorites with the 55gr FMJ W/C are 25.3 gr of H335 or 27gr or BL-C(2). PLINK ALL DAY!

For accuracy in along barrel, I use 75gr Sierra MKs with Reloader 15

You'll need to substitute a load for a similar bullet.

Alliant data shows a maximum of 28.0 grains of RL-15 with a 55 grain Hornady MJBT.

I can tell you that you can't get anywhere near 18 grains of RL-15 into any LC, WCC, Winchester, or Lapua case I have tried, even by dropping with a tube and vibrating the powder down. 27.4 grains fills the case to the top of the case mouth.

So, pick a start load and work up to 27.0 or 27.2 grains. 27.2 grains is probably not a good choice on a progressive loader as too much powder will jump out.

RL-15 is way out on the slow end for these bullets, so the case gets full quickly, but I bet RL-15 will shoot the 55 grain VMAX very well.

The critical language here is "in an AR-15". There are lots of great powders that work well in .223 rifles, but to get reliable performance and to avoid beating the crap oot of an AR 15 with it's non adjustable gas system, you want to stay with something vreasonably close to H335 or BLC-2. in terms oif both burn rate and pressure curves to ensure you have the proper pressure at the gas port. Both those powders also meter very well and are well suioed to larger scale relodaing (progressive presses, etc).

Extruded powders like IMR 4895 don't tend to meter as well as a coloidal ball powder.
