Long range noob here with some questions. Basically I was under the impression that a .308 would be tumbling by the time it reached it's target when shooting out to a mile. Now the reason I believed this is because just last week I was shooting my .338 out to 1585 and having fantastic results. I decided to try out my Warner build .260 just to see if I could get some hits at this distance. I eventually did have about 3-5 hits on a 24x24" steel out of about 20 rounds. Upon inspection of the target there were clearly visible strikes that showed the bullet impacting sideways. Essentially keyhole imprints on the target. So I was bragging to a friend about getting hits at almost a mile and he decided a few days later to head out with his .308 Thunder Ranch. I was not there but he did send me a picture barraging about how his TR was having consistent hits at 1680. And he wasn't experiencing any bullet tumbling. So by my limited knowledge I was under the impression that a .260 would have much better chances than a .308 at these distances. What gives?

My target last week. In the lower left you can clearly see 2 bullet strikes that appeared to have hit sideways. I even found a complete 260 pill with a dent in the side of it as it appeared to have struck the top of the steel as it tumbled to the target. I think a few shots might have hit straight on along with the sideways hits.
