Best powders for .223/5.56?

I just got my Dillon 650 in yesterday and I am starting to set it up to load .223 for my AR. I have owned a Dillon 550 in the past and have loading experience but I have never loaded for .223. I am wondering what loads that you guys are getting the best performance out of? In today's market I can't really afford to buy ten different powders and to figure it out, so this is why I am asking for help.
As I stated before I am loading on a Dillon 650, using Lyman 49th edition and Hornady 9th edition manuals. I already have my brass (Lake city), Hornady 55 grain FMJ BT W/C bullets and Winchester WSR primers. I am preferring to stick with the loads in the Hornady manual as they seem to have a better variety of work ups for the .223 and I already have all the components they used in their work ups except for the powder.
So, I would greatly appreciate any help you can give me as to what the best performing powders that you all use. Thanks for the help in advance.

There's like 50 different kinds of powder and you can't just buy a sample pack to test them out...
I guess what I am looking for is if anyone knows what powders were specifically made for .223/5.56 ammo.
I am shooting a Ruger SR 556.
I may suggest going to different primer when supplies straiten out. Those Winchester are rather soft, good primer, just an AR thing. You should never get a slam fire loading from mag. But are much more likely if single loading and nothing slows the bolt down(like stripping a round from mag).
Tula/Wolf small magnum, CCI 450 or Rem 7 1/2. All work good. I have also used lots of regular CCI. Win just seem the softest.
W748 works great for 50-69g bullets as does 2015.
75-80s RL15, Varget, AR-comp.
Some other good powders were mentioned also.
For that load, Ramshot X-Terminator all the way. Meters well, good velocity with that size bullet. TAC works well to, use if going 60gr or heavier bullets. I would try and stay with a ball powder with progressive, unless it is smaller "kernels". I have used a lot of Accurate 2015 as well.

What primers are you suggesting? Are they interchangeable?
You read some books and they say don't deviate from the work up and then you talk to other folks that say they use whatever primer comes out of the drawer when they stick their hand in it. Can you get away with substituting certain primers?
any of the above powders will give you good decent groups on human sized targets out to 500+ yds.
23.8 grains of IMR8208XBR
with Sierra 69 grain SMK's
for my Colt 1 in 7 twist
tight groups
Tried the CFE223 with OK results.
I use 23.6gr with the same results. [:D]
The next problem is I am having problems with my reloads in my Ruger SR-556. I reloaded to specs in the Lyman 49th edition as far as length of the finished shell and the gun jams up when I try to fire them or just cycle them through by hand, and when I say jams up I mean I'm having to take a block of wood and a hammer and beat the charging handle back to get the round out of the chamber. I sent the gun back to Ruger to see what they could do with it and after some work to the feed ramp they test fired it, sent it back and said that it was working fine. I am still having problems with my reloaded ammo, it is still doing the same thing when I try to cycle it through by hand. I have figured out that my factory Hornady loaded ammo (.55 grain V-Max) is cycling fine, absolutely no problems with it. The only difference between my reloads and the Hornady ammo is the length of the rounds. The Hornady are rounds 2.230 in length and my reloads are 2.260 which are to exact specs of the Lyman 49th edition manual. I did reseat 1 of my reloads to the same specs as the Hornady ammo and it fed through just fine, so I know the jamming problem was a problem with the overall length of the round.
My question is am I going to run into any problems if I seat my bullets a little deeper and get they to same specs as the Hornady ammo? Will I have any problems with increased pressures or anything else that you guys can think of?
Thanks for the help in advance!

Ok, got my Dillon all set up and started reloading, I had to use Hodgdon H4198 powder due to that being the only available powder that I could find to use.

If you don't have them, get a small base sizing die [;)] Ruger puts a tight chamber in their 223,s. Every Mini 14 I've had needed to use them when sizing 223 brass, specially using military fired brass [^]
So factory loads are working and your reloads are not? That tells me your reloads are not meeting the criteria of an Auto rifle's needs.
Remember, not only do you have to have enough power to make the rifle function, you can't over-power the round because it's not like a bolt where you can 'beat' the fired case out of the chamber. It has a narrow performance band that you have to stay in between for the rifle to function by itself.
Of the problems you describe and what appears to be a solution, you have found that seating the bullets deeper makes your ammo work fine through your rifle. The reason is this: The deeper seating allows for a little bit of pressure to be let off before the bullet hits the lands and you have a natural spike. With the bullet seated longer you were hitting the lands right away, and therefore getting a pressure spike right away. The pressure spike made the case stick in the chamber. Even a slightly higher firing pressure is okay, like when seating bullets deeper, when there is a "run at the lands". The higher pressure is okay when it doesn't spike over a certain amount to make the case stick in the chamber.
FWIW, that is the whole difference between a 5.56 and a .223 round. All the dimensions are the same except the 5.56 has a hotter load of powder. The pressure of that hotter load is alleviated when the bullet continues to run down the barrel instead of stopping momentarily (micro-second) as it hits the lands.
Therefore, by what you describe, I think you had too hot of a load seated out too far in a .223 chamber that caused the stuck cases. As the pressure was allowed to be alleviated by the deeper seating your problem ceased.
I havn't had a chance to shoot the rifle since it came back from Ruger, I am still getting the jamming problem while I am cycling my reloads threw by hand. I don't not have this problem with the Hornady factory ammo however...
Mine required small base dies. I tried several sets of dies from different companies before borrowing a set of RCBS small base dies and fixing that problem
The other problem was the crimp. I failed to read the directions and was way over crimping. Luckily. I checked after the first round and had it fixed in about five minutes.
Either problem can cause what you are describing.
