Everybody expects different performance from bullets.Your's are doing what they were designed to do.I read allot of complaints about the CoreLokts.I've been using them for quite awhile. In my rifle they shoot good.Last year using my 270 Win I shot what turned out to be a knot head instead of a doe I thought it was.Using the CoreLokts it dropped instantly.When dressing it out I found the bullet. It had mushroomed out perfectly. I didn't take the time to weigh it. I would say it kept almost all it's original weight.I use 150 gr.The ammunition debate will always continue.If something works for you keep using it. I can't see spending big bucks for something the cheaper ammo will do.I've tried the Federal Premium 130 gr Ballistic Tips in my 7mmRM. My gun hated them. The Corelokts shot well.Yep ! I'm using the Corelokts in the 7mmRM just like in the 270.
