My response is pertaining to Barnes only! How many years ago? Where these the “old” original Barnes X.....if so, the mono’s are a longer bullet with much greater surface area to barrel contact. The newer bullets, are grooved, much like a cast bullet! Less surface contact area, less friction.....less heat! Also, better accuracy, generally higher velocities, and much cleaner to shoot.....less metal fouling! Win- Win- Win! memtb
