I purchased a Ultra Sonic case cleaner and whow!!!! I have always tumbled my 450 brass, but this machine really gets the insides clean. It took several cycles and the solution was so dirty, you would have thought I had fired black powder in these cases. Now the inside necks are nice and clean and not imbedded with burned on carbon (which can function as a lube).

I did notice that even without having the wide spot at the heal like the 275XPB, the 250 FTX was considerably harder to start in the TightNeck. With a good chamfer on the inside of the mouth and persistence, they did start however and had strong, consistent tension as they were seated. That having been said, they is a good argument that the TightNeck process may better serve .451 bullets as opposed to .452 bullets. Tolerances do vary and my experience has been that what a manufacturer calls .452 may wind up being in reality, .451 or .4515. Ditto on .451's running .450 or .4505.
I am conflicted on whether I want to subject my brass to the shrink and stretch process as it may lead to premature case deterioration from work hardening.
