I tried to load some 303 British with a lee C312-185-1R over 8gr of red dot and I was wondering if anyone had any info that would tell me what velocity I am getting. I do not have a crono and I want to keep it a bit slow because I didn't gas check them. Any info on changing charge or trying maybe some Unique powder. As of right now I only have those two. Any help would be appreciated. Thanks
