the Otis kit is great for taking to the range and I use it for my M&P9 barrel
Its a nice portable backup. I keep it in my rifle case.
I dont use it for my bolt gun unless it needs cleaned at the range.

nah, not true. the brass does expand to fill the chamber but it also shrinks back when the pressure drops. not all the way but enough to be pulled from the chamber easily.
when reloading cases for accuracy in a bolt action match chamber, I don't resize the cases at all, only the necks. all case shot in an auto loader get full length resized...
test it yourself. just pick up the empty that has just been ejected and slip it back into the chamber...
or, shoot a brass case cartridge in your rifle with the extractor removed. lock the bolt back, then slip the empty case out with the tip of something pointy (I use the corkscrew on my multitool) or just push it out with a rod down the barrel from the muzzle.
don't try this with steel case ammo though, it's not the same...
I was talking more about the temperature of the brass, and why it's hotter from Semi-Autos
BRB (be right back)...
edit: found it! http://www.ar15barrels.com/prod/operation.shtml
thought it would be more specific in regards to the case springing back close to its original diameter but rest assured, it does. otherwise you would be ripping the heads or rims off the cases, not extracting them...
