Default chairgun

chairgun is a tool bit like a screwdriver but some use them as a chisel. the BC values on chairgun are approx and can and will vary from barrel to barrel. you could go find the bc value for yourself with two chronos and enter it into chairgun which would give a better result. but your next batch of pellets may differ. also note the muzzle velocity may also change with weather/temp/pellet batch.
