Buddy I work with has been working up handloads for his .222 for better than a year. One day at lunch I asked him how he was making out with it.
He says "No matter what I do I can't get it to shoot better than 1 1/2 inch groups!"
I said you mean you can't get that thing to shoot better than that at 100 yards?
He says "No, I'm shooting at 300 yards!"
I used a few choice words on him and explained in no uncertain terms that the wind can account for that easily.
They will shoot -- nice tight groups.
BTW, he was using H322 powder and 55 grain bullets.
