I have had mixed results with the Sierra GK. Only at distance over 200 yards out of my .270 have they worked well. That was the 130g. I have used the 165 Speer Hotcore from a 30-06 on 1 elk at 281 yards. In and out both shoulders. I did use the Speer BT a few times and thought it softer than the GK. Those were out of a .257 Roberts.

I have yet to have a complaint about the Hornady Interlock. I've used several on deer and antelope in .264 WM -300 H&H. I rarely use 150s anymore in 30 caliber but used to use them a lot and didn't find one brand that wouldn't work on deer.
