I had a ridiculously good day. 0.387 MOA from factory .308 is wild to see. And, I even got it on video.
My brain started thinking, and I threw my 24" 1:12 Lothar-Walther barrel onto my green AT308 after doing some research on past Arctic Warfare rounds that were used during its hayday. Decided to get more data from this barrel using Federal T308T 168gr, and holy smokes it did not disappoint. My 300 yard group would have been tighter had I actually adjusted for wind that day. But even still, I'm happy with that group.
Below is the chart I put together from doing some research, as I struggled to grasp what round was most effective for the AW during its prime.
The typed sheet was a printout that came with someone's AWP from what I recall. I never did anything with the data once I found it. But, decided to pipe all of the information into a chart using ChatGPT to better visualize what the real world capabilities were of each round, versus what the printout dictated aka "Doctrinal Cutoff" ranges from the printout. It then also included ballistic data to better represent what each round could do.
I then redid the chart to include what kind of groupings they were capable of, converting the milimeter measurements to MOA, and included that in the legend of each chart.
Ballistics have come a very long way since the hayday of the Arctic Warfare. So all said, it was interesting to learn what the real world capabilities are of the Lothar-Walther 1:12 twist barrels; not only visualizing it in charts, but then going to the range and spending a day pushing limits. I've personally reached out to 950 yards with T308T using a 20" 1:12 barrel fairly effectively on an IPSC. I'd like to see just how tight I could keep things using a 24" 1:12 in the future.
