I just shot a few test loads I had worked up for my 16" lightweight carbine. I was using 55 grain V-Max bullets over several different charges of TAC and Varget. I had one OK group out of the TAC series and I had a couple OK groups out of the Varget series, but neither were particularly impressive. Should I have used Benchmark instead? I know Varget is kind of a slow powder, but I've always heard it's a good accuracy powder as well. I was just wondering if Benchmark might have been a better option since the Varget wasn't quite what I was hoping for.
