My only .17 experience has been with the Fireball.
Mostly I like to load boat tails for varmints in my .22s.
I chamfer my cases, but sometimes those flat base bullets tip sideways in the mouth when I run the ram up. Boat tails seems to stay put better. If you had one tip to the side they would still load, just cut part of the plastic tip off. That is if you did not feel the resistance and balance the bullet better.
On my .17 Fireball I am using Hornady dies with the sliding seater. Works a charm with the V maxes.
