subsonic bullet flight versus supersonic

#Subsonic bullet flight versus supersonic series#

If a shot is faster than the average muzzle velocity, it would strike high, and if it was lower, it’s strike low. “Another problem caused by the rapidly falling trajectory is the sensitivity to variations in muzzle velocity,” explains ballistics expert, Bryan Litz. These aspects are especially critical when first round hits are important.

Topics from previous posts have been relatively straight forward and generally easier to understand and overcome, but the topics in this post can be more difficult and because of that they’re often the differentiators between who gets hits and who doesn’t. In this post, I’ll touch on a few things you need to keep in mind related to external ballistics and the extended time of flight. In the second post, I discussed significant challenges related to spotting impacts and getting accurate target ranges. In the first post in this series, I focused on two big issues related to optics, and highlighted several new products designed to help you overcome those obstacles.

In this series of posts I’m trying to highlight a few things that make extreme long range (ELR) challenging, and pointing out a few products worth checking out that might help.

As your bullet’s time of flight extends up 3 seconds, and possibly even up to 6+ seconds, priorities shift. You’ll face new equipment challenges that may not be obvious. A few factors that could be safely ignored inside of 1000 yards become critical to getting rounds on target. When you extend shots into extreme ranges (like 2000+ yards), you’ll face some new obstacles.
