A good load I have developed is right around 25.0g of WC844 behind a 62g M855-equivalent FMJ-BT bullet. From my 24" Varminter AR I get about 3200 FPS with this load and it is sufficiently accurate. I last tried it at 25.3g and think I will stick with that since it gave increased velocity with still no pressure signs and the rifle cycled fine with no apparent odd effects. I think the COAL on that was near max and still fit in the mags. I need to get more of those bullets.

Thanks from Yooperboy

Since the early 80's my favorite .223 powder has been IMR4198. It works great in 45 grain varmint loads or 55 grain FMJ loads. The issue always has been it meters very poorly. If you want consistent charges you've got to set the measure low and trickle up to the charge or use an electronic powder measure/scale (and you'll get regular overcharges that you have to dump back in the hopper.)

Awhile back I ran across an old (early 80's) partial can of BLC2 (and several others) and while using it up I ran across a very good load for the 55 grain FMJ bullets (hornady) in my rifles. So far it shoots great in all the rifles we've shot it in. Metering is so much more uniform and loading is faster because I can use the RCBS uniflo powder measure instead of the electronic measure/scale.

I random weigh check 5 charges out of every 50, whether loading rifle or pistol. The BLC2 random checks never went above the desired charge and only a few of the 40 checked (yeah, loaded 400 rounds that day) where 0.1 grains below and only one was 0.2 grains below.

A few days later I loaded another 400 rounds with H335 (my youngest son's favorite .223 powder) and of the 40 charges randomly weighed none, right, not a single one, was off the desired charge weight.

Now, for years I've read that you should use magnum primers for ball powders but I never have. Then again, I don't live up north where it gets really cold either.

I still have some IMR4198 but the last two 8 lb. jugs of powder I bought were BLC2.

Just loaded a couple hundred 40gr V-max yesterday using 22gn of 4198 over a 205m primer. Works super in my Savage 112 FSS an old mini 14 and of coarse the rabbit popper ARs.

TBH, I don't think you are going to see a lot of AR reloaders using VV powder... unless it's for a very specific benchrest load or similar. There are too many 'just as good' powders that cost less with better availability.

I run RL15 for just about anything. H4895 is great for 223 also.

Back in 2003 AA2230C Data Powder was selling for $59/8lb. I bought 10 jugs and still have 4 left. It is comparable to AA 2460, and uses the same loading Data. I intended it for 5.56/223, but it also works great in .308 M80 type loads. Very good spherical powder for the 5.56 and it's big brother.

I bought a Quick Measure with a mount for my Dillon 650s to handle my extruded powders. Works Great!

H335, TAC, RL15 and Varget are all good choices.

H335 is what I use for all my 55 grain loads.

I use Varget for my 69 Sierras and 75 grain Hornady bullets.

77 grainers get either RL15 or TAC, depending on the purpose. For match shooting I use RL15, for less than social purposes I use TAC.

Still got another 2lb of win748 to finish up.

26.5gr CCI 400 or 450 pushing a HDY 52gr HPBT gives me about 2850fps from a 16" AR.

Ok I'm down to the big 3 on average bell curve of info from here and everywhere else I could get it, books, articles and the web. If I was doing match I would definitely go on vv. But I'm not! I'll keep ya in the loop on what way I'm going. Gonna play it safe and pick one best for my temps and elevation. I plan only to make 10 at first to insure everything is cycling right and doing what I need SAFELY. Also I'll be measuring every step as I go. Rechecking all of it... I did this in every load I started reloading. My concerns are non eject, head space, neck crimp, and shoulder spacing by making a few dummy rounds and micrometering I should be able to get a solid first round made. After I get this done I think I can start to dialing powder weights to get what I need for multiple bullet runs.

I thank each and everyone who has contributed with the knowledge that you had with experience. Old and new.

Here's the thing.... and this is for 7.62mm and the Socom, so it's not apple and oranges....

I do most of my load testing in NV... in the winter (Christmas) it's around 50-60F, in the summer it's around 100-110F... and I've shot... no kidding... at 124F measured. My velocities usually range +/- 50fps between the temperature extremes, this with IMR4895 and IMR4064; and some variation in my handgun loads, even with factory loads, although not so drastic. It doesn't change my POI much, if at all. The only reason I could see being concerned about temperature stability is in very cold (freezing or sub-zero) temperatures... which you would experience in CO (...and I know all about that, being stationed at Fort Carson at one time.) Unless VV powder is marketed as temperature stable specifically, I would probably look at the powders that are if you are that concerned with temperature stability. I don't have specific data from very cold temps.... largely because I don't go shooting when it's that cold.

Charlie, back in the u.p. it's a huge concern back there for me then. Here not so much, yet if it worked there, works everywhere consept.. I'll continue to use for my other guns just because I have it. For my ar I'm not in those sub zero temps shooting. Sure it gets cold but I'm going another way from vv especially because cost! I'm choosing another because of this. Extruded isn't a concern because I have a trickler, sperical would measure More consistent in my manual micro measurer. I'm going to see a local guy here who owns a tactical shop to see what he has in stock and pick his brain as well. Problem is he isn't open on days I'm off but is available to be open with a pre call. I'm down to 3 as I said before. Since I live here, cost and availability without shipping crap is the game without traveling too far. My local fellow range companions buy his hand loads. I choose to make myself with the most knowledge available I can get on this before I start ramming them through my newer gun. I already had the tools, not the dies for them.
Thanks for the great info! Its well appreciated.

Well got my primers, n powder by driving to get. Yay. Couldn't justify Hazmat charges to ship. Rest I ordered though midway. Midway sent and delivered to gods no was where. Tracking number said on doorstep and was not there. What a Let Down! Had 500 brass ready to go.
Darn I'm not mad at midway but the huge shipping co. They use. This is bullet making stuff and really makes me upset. Yes I tripled checked to make sure it would get to me. What hands are they are in now???? Darn I'm pissed!

Ok

Finally got stuff from midway, thank gosh! Mon. Tues. test day. Running 25 loaded shells per group, to see load accuracy. This will be for 5 different loads of 1 powder. Starting in the middle of suggested load recommended. Since it is closer to what I wish to get to, sooner without wasting ammo too much. Info is info for the future. Check it very close in reloading each group, each bullet. Next reply should be target pics.
Thanks for all the info given.
Talk to ya all soon.
