6.8 SPC 110v-max and bthp powders
As is always the case nowadays, I am looking for some decent powders to shoot the 110 in 6.8SPC. It will be out of a Bison Armory 18" AR barrel, 1-11" rifling. On a Stag upper. I recently found a back door into Sportsman Armory this past summer, that allowed me to put 500 SSA virgin brass on back order at 45 bucks a 100. I had forgotten about this, but just received an email asking if I wanted to extend this back order, same price was invoiced. I am not entirely sure I will even receive these, but I plan on just clicking that extend button every time I'm sent it. This was the first time I've received it.
That being said, I was loading H322 when I last loaded for this round, which has been a few years. I only could find one pound left, I am assuming my other few pounds were liberated by my father over the course of a few years. I just decided on 322 because it worked well first try and was very repeatable. Obviously now I can't find any. Suggestions? I think Rx10 will work, and I picked up a pound of that awhile back, and I have some rl19, I heard it was supposed to be good for 6.5's, so I think I have three pounds just sitting in the closet.
Any suggestions? I don't really want to use up some of my Varget or Rx15, so what else should I be looking towards? Thanks.
