#SUBSONIC BULLET SPEED 38 HOW TO#

Over the years I’ve shot many different 22 LR hyper velocity rounds in a range of rimfire firearms. Personal Experience with 22 LR Hyper velocity rounds They perform just right across the ranges you typically shoot a rimfire. But when it comes to velocity (therefore higher energy) and wind deflection the ballistics of the other rimfire rounds are ideal. The hyper velocity round shoots flatter out to 100 yards, beating the other 2 rounds, but at a price (accuracy usually suffers – read below to learn more). The lesson here for shooters wanting to understand 22 ballistics is that high velocity usually does not equal better downrange ballistics performance. The standard rimfire round is between the two velocity extremes.

The hyper velocity round is affected the most ( 1.09 inches drift off the bullseye at 50 yards) while the subsonic round is least deflected by crosswinds at this range ( only 0.62 inches). This shows the bullet drift at 50 yards with a 5mph crosswind coming from the East (3 o’clock). Look at the column named ‘Deflection(Inches)’. The Standard round lost only 134fps while the subsonic 85fps. Notice how much velocity the hyper velocity 22 round has lost at 50 yards compared to the standard and subsonic rounds – over 340fps! The other rimfire rounds lost far less velocity.

The 22 LR is ideal for teaching novice or beginner firearm owners the basics of exterior ballistics and how to consistently hit targets beyond their usual shooting distance.Īmmunition is inexpensive so you can practice all day at the gun range.

Why Understanding 22 Ballistics is Important Understanding 22 Ballistics (22 Long rifle – 5.6x15mmR) whether you shoot hyper velocity, subsonic or standard 22 ammunition (around 1250fps) is essential if you want to hit small targets beyond 100 yards.
