Some projectiles can be very touchy when it comes to how far they want to be jumped , what’s your guys opinions and findings when it comes to the 77gr TMK .

Don't seem to be fussy, but their ogive is designed to fit the 2.3" AR Mags so do work quite short. Mine are 2.3" OAL out of a tikka regardless that I have a long Waters mag. Seem to get more than enough 2206H in to push them past 2,900 fps (stnd barrel).
