Emptying Primer Tube on 550B

I have been reloading 5.56 rifle ammo on my 550B, and am about to venture off into reloading .40 S&W pistol.  How do you empty the primer tube when switching over from one type of primer to another?

 

First, remove the low primer alarm and follower rod. Next, remove the two bolts that attach the primer feed to the machine. Lift the primer feed assembly off, and invert it over a cup or flip tray, and pour the primers in the magazine out.

I would think it's even easier than that.
• Remove the primer alarm
• Unscrew the knurled primer column cap
• Withdraw the internal primer tube with primers intact

Or, if the powder measure is already missing...
• Spin the primer alarm counter-clockwise, thus removing the alarm and knurled nut at the same time
• Withdraw the internal primer tube with primers intact

The Dillon answer works while the rfwhatley answer will spill primers into the flash tube and some out the bottom and then you can unscrew the two bottom screws and do what Dillon said to do to begin with. Guess how I know?

Gosh, I sure enjoy my Dillon press.  

I will second that removing the primer tube just spills primers everywhere. You would think they could make the bottom cap tight enough to easily change the tube out. Kinda a pain to pull the whole thing every time.
