My 18" 243 LBC is a middie and suffers from gas timing issues. I've been using Benchmark and 95 grain SMKs. Even though Benchmark is relatively insensitive, I'm intrigued about trying Varget given that it's the least temp sensitive powder out there and I should probably be able to get within 50 fps of the 2740 I'm doing now. Will a slower powder make timing better or worse? I think this through in different ways and come up with a different answer each time (including "it doesn't matter"). Benchmark is a relatively fast powder so Varget would be slower.
