I don't like heavy bullets either. A 250grn bullet at 2300fps has more energy or kills better then a 300grn bullet at 1800fps.
BTW-My mountaineer shoots the 250's lights out with 120grns of BH209 and harvester sabots. Nice to see you trying some other products. Another good bullet is the 275grn Parker Ballistic Extreme. I killed alot of critters with those. It's good but not as good as the Lehigh/Bloodlines.
