go with 125 to 130 gr
cappi-
The 125 to 130 grain bullets will all work well out to about 250 yrds. The reason that I suggest the lighter bullets is that they are designed for varmint hunting using high velocity rifles such as 308, 30-06, to the 300 magnums and have thinner jackets so the bullet literally comes apart with it hits the target. At the 300-221 fireball (A.K.A. 300 whisper(r)) velocities these bullets will penetrate and expand like the heavier bullets at 308 etc... velocities.
The 125-130 grain bullets typically have muzzle velocities of about 2100 to 2300 fps @ 1850 ft-lbs of energy. If you sight in for 200 yrd.:
-at midrange the bullet will be about 3.5 in high moving at ~2000 fps with
~1100 ft-lbs energy
-Zeroed at 200, moving at ~1750 fps with
~850 ft-lbs energy
-at 225 the bullet will be 2.5 in. low moving at ~1700 fps with ~800 ft-lbs
-at 250 the bullet will be 6 in. low moving at ~1650 fps with ~750 ft-lbs
This is basically a center mass hold out to 250 yrd.
The typical 0.308 diameter bullets with heavier jackets like the typical 150 grain and above bullets probably will not expand/mushroom as reliably as the light weight varmint bullets
This is my 2 cents, some may disagree but I think the ballistics are basically correct.
