Are you using a Lee Carbide Factory Crimp Die? I'm running 230 cast bullets from a .41 Magnum at 975 with no movement whatsoever... I have also run a few heavier loaded cast bullets through with no problem. The FCD makes sure there is total contact between the bullet shank and the case.

CHL may be correct however...260 grains of lead generates a lot of recoil in a AirLite....
