It has been a few days hasn’t it?
I was hoping to use some H4350 and I have some Hybrid 100 that should work. I tried some Reloader 17 and I just couldn’t get it to group like it should. Of course I have Varget and some others. Mostly Hodgdon powders.
There is no reloading data anywhere that I have found. What little info I have ever received was word of mouth.
