Well i have a marlin 30-30 that will shot 1in groups at 100 yards (factory everthing)

I have a Rem 700bdl 7mm shoots .50 groups at 100 yards (factory everthing)

I have a Savage M112 22-250 shoots .50groups at 100 yards(ditto)

I have a Knight Disc rifle shoots 1in groups at 100 yards (ditto)

Also have a 444. Marlin that will shoot 1.5 to 2.0 inch groups at 100 yards (ditto)

So i think it has more to do with the person behind the gun. I almost forgot

Delt H-Bar 223 1in groups at 200 yards (ditto)
