VAhunter,
I can't remember if I've ever killed anything with a 7MM Rem Mag Core-Lokt. I do have five boxes of very old 150 grain Core-Lokt. I've chrono'd a few rounds out of my 24" barreled 7MM Rem Mag @ slightly better than 3200 FPS. From what I understand, newer Core-Lokts might be a little more tame, not that any animal would be able to figure out.
If I were going to use factory loads, I'd use Core-Lokts.
