Last year at the 1,000 Yard Williamsport Benchrest School, there was a mix of 6, 6.5 and 30s used. I shot a 6.5x47L, while some others shot 6mm Dashers or 30 Win Mags.
Anyone else here going to this years school? Though I am a member of the Williamsport Club, I am thinking of taking the course again this year.
