CCI Quiets are perfect for the Henry. Almost as quiet as shorts - which, for some reason, my Henry Frontier manual says not to use (?): specifically CB (conical ball) shorts.
The key is to get them on sale...I have seen some dealers charging MORE for a round that actually contains LESS, lol...
The guns will fire and cycles them fin its just they are worried about squib loads since some shorts and all CB use the power of the primer and nothing more.
The reason they cost more is that they are specialty rounds and will take time to change the machines to produce these and they can't just run them all year long full rip because it doesn't sell as well
