Back during the shortage on .22 these were the only reason I was able to shoot my Henry. A local store ordered in a whole bunch on accident, they just say ".22" and figured it was money in the bank. I happened to swing by when they were about half way through the pallet, it wasn't selling very quickly since guys weren't positive it would cycle their semi rifles or pistols. I asked the nearest employee, happened to be the owner, if they had any .22 in. He was so tired of looking at his mistake he offered me the rest of the pallet at cost but only if I took all of it. At that point in time I was just happy to shoot and didn't care or know better about keyholes. I'll have to see if I have any left and check if they keyhole out of my Henry.
