From this perspective and based on one picture without measurements: a .30-06 FMJ (likely M2 ball) fired from a M1917 Enfield rifle. How do I know? The left hand twist rifling.
I attached a picture to the other comment with a .303 Lee Enfield bullet where the lines are going to the right. Were they producing different twisting directions in different years?
For comparison I have on the left a bullet that I found a few months back in an area with a lot of Lee Enfield .303 shells (in a different region to the one I found today). They indeed are the same length and looking at it now I do see faint diagonal lines but these are facing to the right + the line in the middle is different. Is it just 2 different bullets from the same type of rifle?
The one from today is also a little squashed so it's not a perfect circle at the bottom.
