Grendel vs 308

[bigbear_98]

Cabelas had some factory sst. I also found one box of the stuff I had. Two different lot numbers and the cabelas stuff was faster. I checked the tracking on my scope at 100 yards up to 35 Moa. That's as much as I could get on paper.

To add more confusion I got a new chrono. At 10' it read 2528 for the old load and 2566 for the new.

I don't know what else I can test to prove my theory. Any ideas?
I guess maybe I can video the targets at distance?
