I see that the promotional .22 on the list is identified at this time as “Thunderbolt” not Mohawk. That suggests the Mohawk nomenclature (at least for .22 ammunition) stopped some time prior to 1984. I doubt if the promotional ammunition’s quality was appreciably, if any, less than the flagship Remington brand, but there probably were some minor corners cut. Putting crappy ammunition on the market under another name would certainly damage the market’s perception of the Remington brand. For example, I don’t remember Mohawk .22 bullets having the typical Remington gold-plated bullets. More likely, the national discount store chains (K-Mart, Woolco, Target, Wal-Mart, and many others of a more local market), would buy much more of it than most any ammunition jobber, therefore Remington had to have some excuse for giving them a better price, that being that Mohawk was an “Economy” brand. Same tactic is used today for all sorts of items, such as supermarket house brands (which are often made by the same large companies that make nationally branded products such as H. J. Heinz, Campbell Soup, Green Giant, Procter & Gamble, etc).
