I would still crimp. The bullet moving aside, the pressure in the case will be adversely impacted by no crimp and accuracy might become a problem.

Besides the fact that you have to use some kind of crimp to remove the flare from your cases, IMR4227 is a slow burning powder that requires a consistent firm crimp for consistent ignition.

buck460XVR is right on the money. Revolver rounds with slow burning magnum powders require a firm roll crimp for consistent ignition. In any case the flare from expanding would still need to be removed with a light pass through a crimp die so you aren't saving a step in the process anyway.

An opportunity to test!
Load a sample with 'no crimp', with 'a medium crimp' and with a 'hard crimp'. Be precise with all aspects of the loads and fire them over a chronograph on the same day with the same weapon.
The results will give you an indication what works best with your selected components and that weapon.
I would bet that with the chosen powder, a crimp will perform best.
Or just put a taper/factory crimp on them and be done with it. I would do the testing but that's what I enjoy.

Looks like it is off to the range for some testing. The current batch I am loading has no crimp as it is new brass. Found 100 Starline at Cabelas for 22$ so I figured what the hell. Sounds like it can be fired without a crimp but I may as well go ahead and crimp. I was just looking for more knowledge and not a reloading shortcut. I take pride in making quality reloads and was just on a fact finding mission here. I in no way am trying to skip reloading steps to save time. If I were to do that then I may as well buy the factory WW box. Thanks for all the info here guys.

Definitely crimp. I use 4227 in many of my 44 mag loads and it will simply not perform well without a firm crimp no matter what pressures you load to. But with a good crimp will do excellently! A very underrated powder in both load manuals and the perception of many reloaders.

ldlfh7,
If you have access to a chronograph, save back 10 cases, crimp 5 hard and no crimp of 5. Then compare.
If you got your brass at Cabelas, if you walked in, that would put you near KCK or Hazlewood. Sunday's supposed to be much nicer than Monday. Unless you shoot inside someplace.
