The Letter analyzes stability of spin precession currents in superfluid$^3$He-B when the precession angle is very close to 104$^\circ$. In this limita spin-precession vortex has a very large core, and a barrier blocking motionof these large-core vortices across the current streamlines (phase slip)disappears at precession-phase gradients much smaller than critical gradientsestimated from the Landau criterion. Nevertheless, spin precession currentsremain stable up to the Landau critical gradients, since in this case there isa barrier, which blocks the phase slip at very early stage of vortex-corenucleation. The Letter also predicts a second-order phase transition between aparity-symmetric and parity-nonsymmetric spin-precession vortex cores at theprecession angle 126.5$^\circ$.
