Reloading 454 Casull: OAL or adjust for cannelure?

[CDRGlock]

I was reloading 454 Casull and set the OAL as recommended by my Hornady Manual.

 

I'm using 250 Gr XTP.

 

However, the cannelure is above the mouth of the case. So do I proceed to lower the bullet to the mid level of the cannelure or do I go with the OAL? Seems like if I lower it, the pressure would be higher which would be a concern.

When I loaded .41 magnum, I lowered the bullet to mid-cannelure,

 

backed off on the powder a bit, and worked up with a chrono
