Military records indicate that Oswald was not a talented marksman

Commonly claimed, but simply not true.

The records show that he was twice rated as sharpshooter and once as marksman.

a far superior rifle (m1 garand) to that of the carcano

According to the FBI's weapons expert who tested the Carcano, it was a highly accurate weapon.

Like all mass-produced weapons, the quality of a Garand and a Carcano can vary depending on where it was made and what conditions it has undergone since manufacture.

That doesn't make him a talented marksman...it means he almost didn't qualify. That is simply a fact.

He "said" it was a highly accurate weapon but his testing data results demonstrate otherwise. (5MOA is not an accurate rifle)

Yes all mass produced weapons have variable quality, however the base quality of a carcano was poor while the base quality of the garand was good. An average garand shot about 2.5 moa or twice as accurate as caraco.
