Try any of the 100- 110 gr "plinker" type bullets.
I've used the Hornady's on coyote and woodchuck in VT.
Both ended up VERY dead before they hit the ground due to the velocity the .308 builds up with such a small bullet.
I messed around with a target load for a while using 110 gr. Hornady SP over IMR4227. They did OK but I never got the accuracy I wanted before I got involved in something else. I'll get back to it sometime. I will be trying some 125 gr. Nosler BTs tomorrow over Varget. I'll let you know how these do. I might end up having to try the IMR4227 with these also. Stay tuned, I am looking for some very accurate results. Both of these bullets should be good on assorted vermin. If I can get the accuracy I will be using it on long range head and neck shots on unsuspecting beanfield feeding deer.
I have used the 110 gr Hornady Spire Point with IMR4064 and Varget. I got super accuracy with it out of my old (lamented) Model 70 Featherweight. It worked great on the woodchucks I used to hunt, but I hope you're not planning to keep the hides. They'll most likely be ruined. Good hunting! IDShooter
My "black-tical tactical" .308 has discovered a new calling in life as a varmint rifle since I started playing with the light hollowpoints. Specifically, the Speer 130g HP and the 125g Nosler Ballistic Tip have given me consistent results. The powders I have used are H380 and Benchmark. A small advantage in accuracy appears to be held by H380, at least from the initial tests, but where I live we have wide temperature variations to which the ball powders appear to be sensitive. I am now loading both with Benchmark, with the bullets seated as far out as I reasonably can (they are short bullets).
Data my friend gathered during a call to Hodgdon is as follows:
Primer: Federal 210
Bullet: Sierra 125
Velocity: 2821 fps
Pressure: 40,600 cup
Velocity: 3070 fps
Pressure: 50,700 cup
Case: Federal GM
Both bullets shoot better than I can, but 95% of the groups I have fired have fallen between 1/4" and 3/4" from the bipod at 100 Yards.
Regarding terminal performance on small game: Bring a sponge.
Don't shoot that one, but from my M14(M1a) & 700vs I shoot the 155's and the 168's from Nosler. The 155 palma's get 42.5gr. of 4064(imr) and the 168 matches get 43gr. of the same powder. I've been using the IMI .308 match brass from Widener's (CHEAP and very reliable). Don't know what they do to critters, but they punch a ragged hole from the M14 & the 700vs.
