Might give the 156 PPU RNSP a try too. I have not used this one but other PPU bullets have surprised me with both their accuracy and terminal performance which is similar to a Corelokt. The price is right. The 139 grain 6.5s looked like they needed the noses uniformed but this made no difference on target.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
