Ryan, this may be of interest I used 2209 in mine with 270 grain Hornady soft points. Somewhere around 76 grains.
The Hornady projectiles have a crimping grove on them so set my seating to give a gentle crimp into this groove.

To set your seating die to crimp each round evenly you want all your cases are the same length.
Screw your seating die into the press with the ram fully up with a case in it.
Adjust the seating stem so the projectile seats to a position where the case mouth is level at just below the top of the cannelure groove.
Now back the seating step out a few turns and screw the die further into the press (the amount here will determine amount of crimp). You can try a bit, then a bit more etc until the crimp looks right,
After you sort out how much crimp you want on this first round then wind the down until and lock it off.

Alternatively, using a lee crimping die will allow you to crimp anywhere on a projectile whether it has a cannelure or not.
