Just read a real interesting article in the newest "guns of the old west" magazine.
The author put a Henry golden boy 22 through a torture test to see how it would hold up.
He fired a total of 28,000 rounds as fast as he could (not all in one sitting naturally). No cleaning except after a couple ftes, he sprayed some lube on the bolt.
When it was all over, he sent it to the smith at Henry for a checkup. The only thing wrong was a broken .30 cent spring, (not to mention a LOT of gunk)!
That's really saying something for Henry's quality!
