any size bullet will work to ony 200yards even the 220gr round nose.
The new low recoil loads were made for 200 yard shots for the youngsters or little ladys ,in the family.
the 165gr is a good all around load......................but the 150gr will drop any deer out to 400 yards if
placed in the vitals.
as for the best bullet..........every rifle has its own weight and brand name of bullet that it likes better than others.
You can a 150 rem,win,norma, etc and find different impant areas and size groups with each one. Some are lucky and get the "Magic Bullet" the 1st one or two tries.
With all the new styles and loads out there today, good luck !!
