I have been happy with the 168 burgers in my 7mm-300win mag wildcat. I am confident that you will feel the same with your 7mm-08 and burgers. As for my 7mm-08 I have been shooting Nosler Ballistic tip's. 120's and 140's. With the 120's My cousin shot a cow elk at 80 yrds and it made it about 30 yrds and tipped over.. My wife smoked a big Black tail buck at 120 yrds with the 140's. It went through both shoulder's and it didn't move.. I do like the BC of the Berger's, but as far as you reasonably shoot while hunting with this caliber, bullet options are huge..
