I totally agree, as for speed perception I think its genetic, some people can detect a difference in speed, and some cannot. As for consistency the difference in forward allowance at 1400 feet per second and 1500 is measured in inches, so is consistency really relevant? I think that components are more important, what i think we are searching for is barrel and cartridge compatibility, the best pattern possible found by trial and error, I bought some cheapies once that took the bottom of the clay out consistently, and left the top spinning time and again, other produce even kills!
