Thanks for the clarification. I load for both and hunt with both, and have since 2004/5, and I’ve always found it interesting to hear how guys develop their opinion to so commonly lump that same assignment on these two - 6.8 = hunting, Grendel = long range...
If I said I felt there was a real difference between the two for most applications outside of the form factor of the rifles, I’d by lying. I’m within a few inches at 1,000yrds, and the penetration difference vs. anchoring speed difference has been nothing better than random for me. With the wrong common bullet in the Grendel and the right common bullet in the 6.8, I have less drop at 1,000 with the SPC than the Grendel.
There’s a slight but undeniable difference on paper between loads, and I do think it gets blown far out of proportion on forums far too often. I picked the 6.8 as my preferred of the two originally, then have changed my preference in the last few years - making the decision both times wholly based on market availability since I don’t find the field performance to be notably different. Most other classic forum comparisons are typically far more significantly different than these two: 7-08 vs. 270, 308 vs. 30-06, 223 vs 22-250, 375 H&H vs. 416 Ruger...
