I have 6 Henry firearms and plan on several more (grandsons, when a bit older). I've put many rounds through the various rim & centerfire guns and have not had any issues.
Some poke at the use of Zamak for the rimfires, but that is of little concern to me, as we are in an age of many alternative materials being used in all styles of firearms. Henry is producing a very handsome, traditional looking gun, at affordable prices. We should be estatic that we should still have companies emerging in the firearm business. Zamak, steel, brass and so forth....reliability depnds on correct processing of material rated for the job more than wrongly perceived notions based on metals alone (please bear in mind I own a powder metal parts making business, and on my administrative staff, I employ multiple engineers and a metallurgist).
