Aim true !
I went out today to sight in the scope on my 30/30. I always take 2 shots to see where im hitting. At 1st i thought i was hitting 2 shots right next to the other. Then i took some shots one at a time then. Checked the target and noticed the it's keyholing. Ran a few factory loads then. Nice round holes. So that ruled out a bad bore. Then some of my loads made round holes too. Strange to me. I was shooting 158 grain coated lead. 9 grains of red dot, And 150 grain speer .308 same powder. I crimped the lead at the lube grove. Did not crimp the Speers. COL was 2.550.
