Generally a distinction for "Canister Grade" powder, Vs. Surplus. A little bit of semantics, I know.
I know it has the de-coppering agent, I'm just not exactly clear that there is a "real" difference other than that; Difficult to get 100% accurate info thus far.
SMP842 was spawned from the military's switch to "no-lead" bullets. As lead free bullets tend to be softer and leave more material in the bore. Notice I only said TENDS, in case there are some die-hard Barnes fans
842 is the replacement powder(replacing WC844) for the M855 round. It is now called M855A1 EPR.
You can read a bit about it here:

Your TN dealer got a website??
Given how old SMP-842 is, and how it came to be; makes me wonder if what is currently being sold as "Surplus" was done so for a good reason/formula change.
I have found that the Dogtown and Varmint Extreme bullets are good to me for around MOA and a little under in my 223 and 204 cal. For general shooting, rabbits, etc. they work just fine. Nosler makes them and they are a basic cup/core bullet. As for precision/benchrest probably not. Go to a couple of the premium bullets. But if you burn bullets, as I do, for rabbit and little varmints in the sage and woods, the other two work just fine, for the price. Bill K
