Re: 1/2 moa guarantee from the factory ?
Test targets mean nothing, here's the 3 shot test target that came with my HS precision that once I got it wouldn't shoot under 1.5" with the same ammo, and had to be re-barreled by HS. In addition I verified with HS that it was shot at 100 yards, by a human, and off bags in the stock. Could it have been damaged somehow in transit to the dealer or myself....possible but unlikely. Not to mention I was stuck with return shipping and insurance costs.
I put more faith in guns that reliably get good accuracy reports such as the sakos, tikkas, remington LTR/XCR/PSS etc. That I do in accuracy guarantees from any factory.
Look at the misleading marketing that Cooper does. They make a good rifle but they encourage dealers to put up their little test targets next to their rifles on display. Test target has all kinds of info on it EXCEPT the yardage it's shot at which is something like 27 yards indoors. Why don't they list a yardage? Because they know customers assume it's shot at 100 yards, I've even seen dealers tell customers it is. Last I heard Kimber removes the action from the stock to do their accuracy testing and at 50 yards and doubles the group size.
What I don't like about test targets is while it's buyer beware these manufacturers are twisting the details and methods to extremes to mislead customers in thinking they are getting a rifle that is proven to shoot to a certain standard.
Accuracy these days is a key concern for many customers and even with factory rifles well over $1000 accuracy and consistency even with test targets is a crap shoot. It sucks in your average buyer who believes the gun makers are honorable and wouldn't use such shifty misleading practices.
Do you drop $1000 on a nice factory rifle and you don't know if you got a 1/2" rifle or a 2" rifle, worse yet if you got the 1.5" rifle even *IF* you send it back their testing procedures might be manipulated in such a way that that they can make it pass their test.
