Another advantage is that some RN bullets have a lesser bearing surface compared to the corresponding spire point, and will stabilize and shoot accurately in some rifles that will not shoot the spire poit well. Helps when you are looking for more bullet weight for brush hunting or areas where range is limited, but you want to maximize bullet weight.

Hello AGW:
I always enjoy your posts.
However, I fail to see how, LESS Bearing Surface could result in greater bullet stability.
A RN bullet is SHORTER, than a Spitzer bullet of the same weight, and therefore more stabilized, if the twist is marginal, irregardless of Bearing Surface.
Bearing Surface effects pressure, but not stability. (Unless perhaps, the bullet is slipping the lands, and MORE bearing surface helped the situation.)
In any case, one would expect a RN bullet to have MORE Bearing Surface than a Spitzer of the same weight due to a shorter ogive.
An example would be�
The 244 with the 1-12 twist wouldn�t stabilize a 100 grain Spitzer bullet. Speer made the 105 grain, RN bullet that would work well in the 244 because it was SHORTER. (Spitzer bullets of this caliber/cartridge, over 1 inch in length would not stabilize in 1-12 inch twist.)
