tapered bullets were designed for ease of breech-seating, they work just as well with smokeless or Bp. Normal chambers are used with these. Many persons did not not want to have there barrels throuted to breech-seat groove sized bullets, so a taper-bullet was the solution.

  As has been mentioned tapered bullets can be used in standard or specially throated chambers.

My thinking is that throating should be done to exactly match the form of the bullet if you are going to breech seat. This will then exactly set the bullet into the barrel parallel with the bore and the required distance ahead of the case minus a very small amount so that seating can be done with a simple hand seater such as you've all seen old Ideal ads for. Top that off with a bump swage to square the bullet up and you'll get all the accuracy the guns capable of....... if you do your part of course! 

  Waterman..... I don't understand where you have gotten the idea that pan lubing leaves something to be desired. A lot of top shooters do this even if they have straight sided bullets that could be run thru a luber-sizer.

  But if that's a hassle for you tapered bullets can be easily lubed using a Pope style hand luber such as our own "Singleshot" makes.
