Anyone done any testing as to the accuracy / runout consequences or effects of the Hornady Lock N Load Die Bushings system?

I have one Rockchucker that is converted to the Lock N Load bushings and honestly the ease of swapping out dies is stellar. I kept another Rockchucker set up for conventional screw in dies for my accuracy reloading work. Only problem is now that I have used the Lock N Load system, screwing dies in and out like the old days, is wearing thin. I am contemplating converting the "accuracy" press to the Lock N Load system as well.

Thoughts?
 
I've had some issues with the lock and load sleeves chipping and starting to develop play. Seemed like 223 was pretty hard on it.

Good news is Hornady sent new ones for free.
 
Do it :)
You might want to check ram height between the two presses so the presses are the same. Shim so they are the same in the ram up position.

No matter what I'm gonna dedicate one press to 308 and 6BR and keep the same shell holder installed all the time. I recently discovered a bunch of sized cases that were too long. I think I may have used different shell holders.

Where did the sleeves chip?
 
I upgraded my old lose Lyman Turret Press for a Rock Chucker about a year ago, i set up with the adaptor busing from LEE and am using the Lee Breech-lock system. So far, so good. I am presently only doing 6.5 x 55 and 9.3 x 62; but I am resizing .30-06 brass for the 9.3; so they get a bit of a work-out.
 
I've been satisfied with the BTO length variation I get while loading on a Rockchucker with the Hornady quick change die system and my seating die. Heck, this is the only die I run in this press, so I don't even use the quick change feature. But I still keep the quick change installed.

I suppose it would be an interesting experiment to try removing the quick change and compare the BTO length variation.
 
I never understood the time saving appeal of the lock and load, nor see it as an advantage to accuracy.
Not like screwing in and out a die is some difficult time consuming chore lol, takes what maybe 10 seconds?
I never timed myself on how long it takes me to load 50 rifle rounds, do it in steps over a few days. Lube/size/trim/clean/prime portion takes at least an hour, maybe 1.5hrs.
Then dropping powder, weighing charge, seating bullet...little less time, maybe 30 minutes there.
So a lock and load die switch takes 2 seconds say, vs 30-40 seconds for screw in dies.
So I could shave 28-38 seconds off a 2 hour process...not sure you could sell me on that lol.
 
You would need to use the Lock N Load system for a bit to understand its benefit. It's not a time saved sort of thing. It's a having to screw and unscrew the fricken die each time. The Lock N Load is 10x easier and less annoying.

I suspect that Lock N Load QD dies system is likely not as accurate. However it is so much less annoying than screwing dies in and out that I am willing to risk a small loss in accuracy.
 
I was looking to purchase a threaded sleeve to turn my LNL single stage into a normal press since I really only use it for rifle cartridges now.
