Improving Accuracy of .223 Loads?

[243winxb]

testing at 200 yards?

When workiing up loads and testing, i would think 100 yards would work better. Even with wind flags, if you miss a condition, wind change,the groups can grow fast.

Two different loads with 80-grain bullets did no better than 3 MOA.

My vote is the barrel is truly shot.
