I have known of this 2.50" Hornady 410 Bore buckshot load for several months now, and I am not sure how long it has been around except that it can’t be older than 2008. It is Hornady index #86239 and is an exclusive order for somebody which does not appear on the Hornady website, but being one digit greater than the index number for their new Critical Defense 410, I am left to assume it is new for 2013. The box says “000-buckshot” and also has the ubiquitous industry-standard misnomer of “410 GA” on the label. I opened one up and found that 2 of the buckshot were 94gr 000-buck, but 2 of them were smaller 64gr 00-buck.
I called Hornady to ask about it and the tech-support operator said this was normal and that they were a custom duplex load - the label just doesn’t indicate this. This is the first time in a modern Judge/Governor oriented .410 load that I have seen 2 different buckshot sizes loaded. Headstamp is “410 410”
These seem to be very rare according to all the Google searching I have done for them and I find little evidence of their past or present existence. The only images which come up are from Palmetto State Armory and Ammo.net. Palmetto is where I first noticed them several months ago, and they have always been out of stock. I noticed Ammo.net just last week when I did a new search and at that time they showed over 50 boxes in stock, but now just a week later they are out of stock. I ordered only one box which I received today. It is interesting to note that the listed fps of 675 is by far the slowest velocity .410 buck out there as all others from Remington, Winchester, and Federal are all listed at 750 to 1300 fps. My guess is that these are not likely to be produced by Hornady again since they are now marketing their Critical Defense .410 triplex load which has yet to hit store shelves.
