Accuracy values for the main guns - MBT's.

"One other thing, how do you un-load the tube of a 125mm gun with the auto-loader if you have the wrong ammo in the tube?"

Exactly in the same way an Abrams would do.You fire it.
Even if theoretically possible, you do not unload a "wrong" round in the middle of a battle in any other way.Too dangerous and time consuming.Even with an human loader the procedure is fire and reload, if I have undestood correctly.

"The info on Russian auto loader equiped tanks ROF is optomistic at best."

Do not underestimate Vasily, that would be a big mistake...
Ten seconds is basically the worst case scenario for the slowest autoloader type, mounted on the T-72.The one mounted on the T-90 can cycle faster, the T-80 is faster still and the latest bustle autoloader is even faster.
So it depends on what specific tank you are speaking about,the loading plan and the mode of operation.You can go from 10 seconds down to probably 3-4 depending on all the above variables. The issue is a bit more complicated than "ruskies SUCK!!!!!!".You should read more about it, it is rather interesting...
