Lube groove on lead bullets. Crimp?

[g.willikers]

It's supposed to aid accuracy if the bullet is as close to the barrel as possible.
So, using the maximum overall reloaded length that fits the cylinder aids in that.
But the less bullet that's in the case might mean more crimp is necessary to keep it there during shooting and recoil.
Here's a quick and dirty way to help decide how much, if any, crimp is needed for your .44 Specials.
Load the gun with all chambers filled and then fire all but one.
The faster the better.
Check the aol of the remaining unfired round from the cylinder and see if it's gotten longer.
If that one is longer, then more crimp is needed to prevent bullets trying to exit the cases under recoil.

For a 44 spl you don need a crimp.
You only want to take out the flare.

Is that taper or roll?

Take an empty case and run it up into the crimp die, enough to feel the crimp being applied. Remove the case and look at it. A roll crimp will round off the case mouth inwards, ie.; "roll" the case metal smaller. A taper crimp will be a straight swage that "tapers" the case mouth smaller...
