Grendel vs 308

DON’T TAKE ANYTHING FOR GRANTED! The bottom line is to deal in absolute fundamentals, measure them, and remove all the assumptions. Don’t ever assume that something is what it says without measuring it. – Bryan Litz, Applied Ballistics for Long-Range Shooting


I took my information for granted. I had ordered a whiz wheel from Accuracy first after taking their class and getting what I thought was good data. I used the 123gr sierra match king as a reference to get my BC. It was what they told me to use, and it was pretty good. I have since refined what I see as good.

During this class I was having scope trouble. The scope at the time wasn't tracking true, I was uncomfortable behind the rifle, and the classroom provided Kestrel I was using kept crashing. I took the data that I had gathered from the class, thinking it was correct, and used it. It has been close up to 750 yards but not perfect. I jumped the gun so to speak by posting what I did in the beginning of this thread. I was only showing what I had thought was my real data.

I have shot a lot of rounds and hate being wrong. And when I'm wrong I like to fix the problem, find out what it was, and share my findings.
