Noticed today that my 22-250 had a few rounds keyhole.
Standard load is Varget and 50gr V-max doing 3900fps. 95% of them shoot fine but out of 30 rounds I had 2 keyhole
Also, loaded some 50gr Sierra SP and when I got near max with Varget (36gr) all 5 rounds keyholed. Loads from 33.5 and up fired fine but when I got to the 36gr loads they all went haywire. I used the printed COL for this load as well.
Is it something I'm doing or is my barrel suspect?
