About a week ago i posted about how i spoke with Marlin Customer service last year about ammunition brands to use in there rifles . They told me only Rem ,Win.,and federal were to be used . With many more companies out there producing ammo now i called NEF today and spoke with there customer service rep. They told me we could use any ammunition maker as long as they loaded there ammo to saami specs.When i asked about Buffalo bores 45/70 magnum ammunition as they are loaded above saami specs, they told me that there ammunition was safe to use in the handi rifles and that the 45/70 handi rifle strength is based on the same specs as the current marlin 1895 and winchester1886 therefore any ammunition made to be used in those two rifles are safe in the handi rifle. I thought i would just pass this information on to you guys who didn't know this. I myself was not to sure about it. Later Tanoose
