Your lack of success may have nothing to do with the powders you are using. Over the summer I picked up a new Kimber Longmaster Classic in 223 Remington. I also picked up some Nosler 55 grain Ballistic Tips and Hornady 55 grain V-Max bullets. I tried Varget, Reloader 10x, H335, Win 748, IMR 4198, H4895 and BL-C(2) powder and CCI 400, CCI BR4, Federal 205, and Remington 7 1/2 bench rest primers. I loaded every combination you could with the different powders and primers. The Nosler bullets shot better than the Hornady bullets but neither was anything to brag about, about 3" groups at 100 yards.
I was highly frustrated thinking the gun was just not a shooter. For grins and giggles I loaded up some 40 grain Ballistic Tips that I had on hand that I use for my Fireball and couldn't get a bad group no matter what I did. All the combos I tried with the 40 grain bullets were one ragged hole so I knew it wasn't the gun (he said with a sigh of relief after having spent $1200 on the gun).
The quest for another bullet began in ernest. I ended up with Sierra 63 grain spire point flat base bullets over a max load of H4895. The load is scarry accurate. I'm talking slightly elongated holes from 10 shot groups at 100 yards. Another bullet that I found to be very accurate is the Speer 70 grain semi-spitzer but it has to be seated deeply in the case. If I were to use the 223 on deer sized game the Speer would be my bullet of choice. For everything else it is the Sierra bullet.
I'm an avid reloader, doing it for more years than I care to admit in public. My gun is a 1:9 twist like yours but no matter what I did I couldn't get the 55 grain bullets to shoot worth a darn. That's not to say the bullets are crappy bullets, they're not, I shoot them in my Fireball with great success. That gun has a 1:14 barrel twist and shooting the 55 grain bullets over a top end powder charge of LilGun is a sweet load for that gun.
You might consider trying a different bullet.
