[QUOTE="Mikecr, post: 958904, member: 1521"] Guess it depends on your standard of 'things'... Given exposed killzone for a groundhog(for example), and a little better than 1/2moa system(which is a whole bunch of 'things'), 600yds is challenging enough. No need to delude yourself over random ranges near 1kyd+.. You don't adjust muzzle velocity to compensate for an error in BC. Muzzle velocity does not change with air density,, effective BC does. Measure muzzle velocity and enter what you measure. Measure your scope adjustments and enter them. Measure distance to several range targets. Measure or obtain air density parameters and enter them. Enter BC until it's right with results for conditions. AND NOW THAT'S KNOWN. [/QUOTE]
