Been using Sportsmatch mounts since the 1980's on all types of harsh magnum springers, never had one fail, sold numerous amounts of these over the years and never a complaint. With that said, there are a number of better quality mounts being made today compared to 30 years ago. No matter which mount you choose, improper installation probably causes the most problems with a mount. Take the time to do it correctly the first time and you wont have an issue. Also consider the scope itself....you cant blame a mount on a cheap or poor quality scope when it fails.
