For 2020 I am returning to shooting a 6mm Dasher for 600 yards. I have shot the 6 BRA for the last two years and I just could not get the hang of it. It is probably me but after long consideration, I am going back to the cartridge with which I had success. Originally, I planned to quit after this year, but traded for a new 7.83 twist Brux barrel and decided to have it chambered for the Dasher. When I wear it out, I am definitely quitting. Also, I have struggled to find good lots of H4895 and Varget. For 2020, I plan to use Re 15 or 8208 XBR.
