If the ammo has been loaded awhile, run the ammo through the seater die a seat the bullet a little deeper breaking the seal. It sometimes making bullet pulling easier.

When there's nothing but ogive to grab, making it smaller than the minimum collet diameter is a step backwards. Well aware of the tricks such as that or a dab of lapping compound to increase friction.
There are situations where a collet puller just doesn't get the job done, or destroys the bullet. Lightly seated bullets with lots of bearing surface above the case mouth are not a problem for any collet or pinch puller. I have a collet puller, it ain't gonna work, ain't used a kinetic since the 80's.
Thanks for those who responded to the question.
