I've seen some with 3 shot groups between 1/4" and 1/2" with cartridges suitable for most hunting (like a 30-06).
Aren't Cooper's test targets shot in a 50 yard tunnel?
From Cooper's website. My understanding is that rim fires are shot at fifty yards but center fires are from 100.
Based on our popular �Varminter� with the addition of the Montana Varminters "Buick holes" and the proven strength of laminated wood, the Varmiter Laminate is an instant hit. Available in our Model 21, 22, and 38. All Varminter Laminates are single shot bolt action rifles that present superior accuracy in a variety of standard and wild-cat cartridges guaranteed to shoot 1/2" 3-shot groups at 100 yards (test target proving rifle accuracy included with every Varminter Laminate). Also available left handed.
