Velocities are going to be based on several things, most importantly what load you are using. You build the load. You can drive the projectile at any velocity you are able to, but if the cast slug is going too fast it can strip through the rifling, keyholing or disintegrating in flight, and very likely leaving leading behind. Follow normal loading work-ups with lead projectiles.
Gas checks are dirt simple - when sizing the boolit, snap the gas check on before raising the ram on your Lee sizer. The action of the sizer will fit the gas check on snugly.
