I have only been installing them for the last 8 years so not all that long but in that time to me they seem to be very good metal. They are about like trying to form leaf springs. I had to make up some special tools to tune them up. They need the edges deburred so they don't scratch up the brass. I have found they also need tuned for release point and tension so they can be loaded properly. To fit longer rounds that don't fit right in a short action or on the longer magnums like the 7Stw and 300 Rum they are a godsend when trying to get high B.C. bullets out near the rifling.

Watch out for the Wyatt boxes sold at PT&G. They look similar but are made to different specs and not in a good way compared to the ones sourced from an authorized dealer or from Wyatt directly.
