Over the years I’ve killed a lot of deer with core lokts and fed blue box. Some rifles shot them exceptionally well while others just sufficient for hunting. I’m going to use 150gr sp (the round nose version) in my 270 win this season for whitetails and I’m sure they will work just fine. I wouldn’t hesitate to deer hunt with any cup and core factory load. Any of those through the lungs will kill a deer.
Funny how barrels either love or hate various rounds hey hotsoup?
I have found over the years, that whenever I buy a new rifle it's really worth it to buy several different boxes of ammo and test them in your new rifle, to discover which brand your new rifle loves. Once I discover that I typically buy 5 to 10 boxes of that ammo with the same Lot # and I am good to go for years.
I do not shoot enough to justify loading my own, so this initial investment in testing is money well spent :o)
