I'm struggling to get my rifle/scope to zero bang in the middle of the target. It'll group nicely about and inch or so away from the POA and after adjust the the reticle the POI never seems to move to exactly where I want it, i.e the middle of the bull. As I say the groupings are really good. It's a a new rifle with maybe about 45 rounds gone through at this stage. Am I doing something wrong? I've tried the cleaning the barrel approach after each shot, and then every 5 shots, and I've tried just leaving it with out cleaning. It's a .308 Howa, I've tried several brands of factory amminition and I'm now considering reloading my own. It's getting a bit expensive and frustrating keeping on throwing lead at the target. I just want to be confident that the bullet is going where I want it to.
Do I just need to let it 'run in and settle down on it's own?'
