So, I checked and rechecked everything last night, changed the scope for a cheap hawke one that I bought for my .223 and went out to shoot a group this morning. By the time I had it somewhere near I was out of bullets so only managed a three shot group (pictured) which has two in the same hole and one very close to it. I’m going to go and buy some more bullets this afternoon and see if it was a fluke or not. Hopefully that’s it sorted and I won’t be without a rifle!
Fingers crossed it’s sorted!
Out of curiosity, did you boresight the Hawke scope before you first shot the rifle with it attached? I’ve not normally found myself that far off the target when I’ve bore sighted a scope prior to use!
