.308 Light Bullet Comparison
Q I've been reloading my .308 Winchester with the 130gn Speer bullet to 3000fps while my mate loads the 125gn AccuBond to 3100fps. Although I can't see any difference in killing power on pigs and goats, he claims his load with the lighter bullet shoots flatter and hits harder because it has a higher ballistic coefficient - .366 against .263. Both rifles are sighted-in 2-1/2in. high at 100yd. What do you think?

A That’s an interesting comparison! But your mate is right when he claims an advantage for the 125gn AccuBond over the 130gn Speer. From the same zero, at 300yd., the 125gn bullet retains 2352fps, drops 3-1/2in. and delivers 1535 ft/lbs of energy. The 130gn Speer drops 3in. more, has 2012 fps and 1168ft/lbs of energy left at 300yd. But the 130gn Speer bullet drops off rapidly and at 400yd. is traveling at 1733fps with only 867 ft/lb compared with 2129fps and 1258ft/lb for the 125gn AccuBond. In the field both loads are adequate for pigs and goats over normal game ranges and you'd only notice any real difference beyond the 300yd. mark.
