Normal for bulk ammo or CCI std vel.1 inch group at 50 yards
When i get a new case of 5000 rounds in, i test rife in both bolt actions rifles. If groups are 1/2" or almost, the lot gets put aside for rifles only.
When testing- 1.Use wind flags.
2.High power scopes with Parallax adjustment.
3. Clean when changing ammo lots or type. Not all lubes work with each other.
4. After cleaning, fire at least 5 fouling shots. 10 is better.
This sounds like work, but its just an excuse to shoot more to me.
