Well, I don't know that is is the case lube, but the only two things that have changed are the press and the case lube and I have to start somewhere. The case lube is the easiest variable to start with. The only other possibility that I can think of that I just screwed up when I setup the dies on the 550.

These may sound stupid, but all have happened.
Case lube: try NOT using any for straight-wall pistol cartridges (assume you have carbide dies and not the old all-steel dies from pre-1980). I have only ever needed case lube on 9x19 cartridges and then, only about once every few years for no reason I can determine (as, the next day, no lubrication was needed).
I STILL prefer my RCBS lube pad and lube as I have NEVER had a stuck case in over 45 years. Perfection like that can not be beat. I have also never needed any lube inside the case mouth as all my expander plugs for bottleneck cases just "glide" up without issue.
Next, isn't the Dillon lube a spray that you allow to dry after spraying for 2-5 minutes and thus should have NO effect on powder?
Did you WEIGH your charges being thrown to verify that your powder measure was throwing consistent and correct weight charges and keep checking every ten round or so until you KNOW things are going well?
Do you inspect powder height in every case before placing a bullet on the charged case to verify the powder height is consistent?
Did you first clean the powder measure and that cycle a whole hopper full of graphitized powder through it for internal lubrication (a hopper of graphite powder also works well). I like to clean all plastic parts with warm soapy water and allow to air dry (don't rinse as the residual very thin film of soap prevent static cling) and clean all metal parts with the Hornady Cleaner and Dry Lube (again, I let it air dry to keep the dry lube on the parts.
Did you ensure that the Dillon measure had the correct charge bar installed for the weight of powder you were throwing (there are, I believe, extra small, small, large, and magnum charge bars)? I ask because so many people have cursed their measure because they have the rifle metering unit installed instead of the pistol (and vice versa).
Did you completely re-set all dies to the new press. Known some folks who think you can just switch dies from one press to another without any issue.

This is an old thread but I'm curious if you were able to fix your accuracy problems.
From what I've read, if there's too much case lube when fired, the round will slam back into the breech before it has time to expand to the chamber and this could cause your bullet to have a longer jump to the rifling and therefore hose up your accuracy. Were your fired rounds covered in powder (on the outside from the neck back) after they were ejected? That would be a sign that your cases weren't expanding in the chamber properly. You could also check the fired primers to see if they were flattened during firing.

I'm also no sure about case lube being an issue. However, if you are going to change lubes for your .223, do a search online at spray case lube "recipes". I make my own using alcohol and lanolin mixed in a spray bottle. It is less expensive and works as good or better than Dillon and one shot.

FWIW- I've never used case lube on straight walled cartridges. I do use chrome polish and a dollop of liquid furniture wax in corn cob to finish the cases. Nothing I use has ammonia in it. I'm not saying this is true but my firm belief is that once the wax is on the die everything that comes after is good to go. Nothing wet like case lube ever comes close to my dies. I use a Loadmaster so obviously I'm not working towards perfect consistency, just volume. So, YMMV

Well, I haven't had a chance to work up new loads yet because of how much travel I have been doing for work, but I am beginning to think that the accuracy issue might have been me. And I think the SD is more the load than anything else.
(mm and 45 are fine. Not sure what the issue was there, but the velocities came back up to what the normally are and the ES/SD went back down to what they normally are (SD in the low teens).
For 223/5.56 I am planning on working up new loads starting a ladder slightly below my current load and working up to about half way between max for 223 and max for 5.56. The rifle is chambered for 5.56 and I am using LC brass so there should be no problems, but I will still be watching for signs of pressure. I am also going to try some AR-Comp and CFE223 and see how they compare to TAC.
I already know that my previous powder measure (Lee Auto Disk Pro), while very consistent, didn't give me the flexibility of fine tuning my loads and I know that the load I am currently using is not optimal. I figure I am probably just better off starting over again from scratch now that I am using a powder measure that has shown me that it has good consistency and gives me the ability to fine tune my loads.
I will have some time in February and March and am planning on using that time to see what I can do.
As for using case lube on straight wall cases... The only straight wall cases I reload are for handgun, and no, I do not use any case lube for them. The only calibers I am using case lube for right now are 223/5.56 and 308 Win. Of course, I don't have any straight walled rifle calibers anyway, but I believe that it is also recommended to use case lube with them because of their length. Does anybody know about the straight walled rifle cartridges, like 45-70? Do they still require case lube?

OH, well, I can't be of any help then because I don't reload rifle calibers. I'm thinking of starting with 7,62x39's because all my AR's are in this caliber. I simply like keeping the number of calibers to a minimum. Right now it's 9x19, .38/.357, and 9x18. But since I'm gaining in rifles I need to start thinking more seriously about rifle caliber reloading.
Regardless, I don't reload with the intent to punch one hole in anything with multiple shots, I don't see well enough for that anymore. I hit my penny at 100yards one time with open sights, just like I bowled a 300 one time while sober; those will never be repeated again in my lifetime.

I've never seen or head of carbide dies for .45-70. I used to reload for it, and still load for .45-90 and .45-100. The cases although called "straight-walled" have just enough taper to rule out using a carbide resizer.
