I don't see anybody using Benchmark. I'm just starting with the Benchmark in the 243, and haven't quite got it tuned in yet. I had to switch from Varget to Benchmark in the short barreled 22-250 because it wasn't burning quick enough, but not sure yet how it will work with the longer barreled 243. I load IMR 3031 for my friends 243 100gr bullets, and it works very nice, but never tried it on the light bullets, but it is listed for the 60gr.
