Ok first of all crimps are for autos and large calibers.
second ideally you should start loading as long as you dare to shoot. Preferably jammed into the rifling.
Reason being this will show you max possible pressure for charge weight. As you work away from the rifling pressure will decrease.
if you are not a target shooter then chances are you will never run a bullet jammed. In this case I would start .005 off the rifling. Any closer things get erratic.
Work back from there...

If your space is limited in your magazine then load to the longest you can fit if your intent on using it.

Doing it this way you wont have issues with pressure spikes and most of the time these guns shoot best close to the rifling anyhow.

Of course some chambers just wont allow for this.
