my preference in my couple 260 rems is the 120 bt.until it fails on me thats what i'll shoot in them. when/if the 120 bt fails to do what i require i'll switch to the 125 partition or 130 accubond and won't check up. all that said the 120 bt is about as good a combo for speed/accuracy and on game performance there is in the 6.5mm realm imho. the 129 interlock ain't no snoozer either but alas...................big H has seen to NOT factory load the 129 interlock in my fav 260 rem.
good luck picking projectiles,
Big Ed
