I have reloaded a few/couple hundred 124 gr. 9mm Nukes and have found them to be excellent bullets. What little expansion testing I've done (water jugs, 12 oz sodas, wet magazine bundles) they are equal to and seemingly better than the Hornady and Nosler bullets I've reloaded (and excellent pricing and customer service). I have some 115 gr Nukes, but haven't done any "testing" yet, and I expect excellent results from them too.
