It will depend on your pistol. Some pistols like SWC bullets loaded long to feed from the magazine, but others won't tolerate any of the bullet extending beyond the mouth of the case, due to short leades, or throats, in the chamber.
My 1911's and Witnesses will allow the SWC bullet to be seated out about 1/16th of an inch, but my XD has a short leade, and won't chamber them. You'll have to experiment with a few loaded rounds and see what your pistol likes and then go from there.
Hope this helps.
