Battue you pose a good question. I ran a quick calculation using the speer .308 cal 150 gr. RN vs SP only changing only the BC of the input data .266/.389 both loaded to 2750fps scope 1.5 " above the bore, zeroed at 150 yds and found the following trajectory comparisons in inches. RN/SP:

100yds 1.0/0.8

150yds 0/0

200yds -2.6/-2.3

250 yds -7.2/-6.3

300yds -14.1/ 12.1

At 300 yds both easily exceed the 1000 ft/lb energy level which I see commonly recommended for deer.
Finally to answer your question I will probably continue to shoot SP bullets in my 308& 30-06 because in the past I have bought a bunch of bulk bullets which are commonly SP design and until I use them up well lets just say I'm cheap. On the other hand I do have about 40 of the 150 gr RN speers so I think I will load up a box for use in my 308 and given I have way to many deer rifles that I rotate thru that will probably cover deer hunting with that rifle for several years to come.

Oh and if you want to change the zero to 200yds you can have a point blank hold out to 250yds. or so with either. The poi will gain about 1" at 100yds and not exceed -4" at 250 yds for either bullet.
