I am a 1000yd benchrest match competitor aa well as gunsmith/rifle builder/cerakote applicator.I have built a couple PRS chassis rifles for customers over the years. In 1000yd BR we have to single load one at a time and we do 10 shot record strings. Shooting as fast as we can before wind conditions change. Many of us running Dual port Kelbly, Bat, or Borden actions, some run drop port and most get all 10 rounds down in under 45seconds. That being said I had no idea how fast guys shot in PRS even being able to have rounds in the magazine that was quick. Difference is crazy what a good custom action with slick working bolt and effortless bolt close on a cartridge.
