Zeroing your Competition Rifle for Accurate Long Range Shooting with SuperChrono Acoustic Chronograph
By: Colton Cerino, Ohio Outdoor Journal Field Writer
This week, I will be shooting in the Blue Ridge Mountain 3-Gun Championship at Rockcastle Shooting Center. To get my rifle ready for the match, we headed south to Thunder Valley Precision in Kimbolton, Ohio. This is one of the few places in Ohio you can shoot long range, all the way out to one mile.
To start out, I set my NRA Zero shooting target 50 yards from the cement shooting bench. On a small tripod between the target and myself, I placed our new Superchrono acoustic chronograph purchased from RiflesOnly.com. As the bullets pass over it, the chronograph calculates their speed. With someone on the spotting scope calling out my shots, I was able to chronograph the ammunition while also getting my 50 yard zero in no time flat.
Once I had my zero, I checked the chronograph for the average speed of my bullets. Using that information I was able to enter the data into a ballistics calculator on my smart phone and calculate the bullet path out to 500 yards. This was an easy way to get the information I need to make those long range shots next week. Isn’t technology amazing?
Once I had it all dialed in, I was able to practice shooting some long distance targets. We set a variety of steel targets from Travis Gibson at MGM Targets and Brad Brune of Challenge Targets out at distances from 200 to 500 yards. Knowing the zero of my rifle and the speed of my bullets gave me the information for my trajectory to take the guess-work out of making those long shots. In a standard, professional 3-gun match, targets range from ten feet all the way out to 500 yards. This is why it is important to know how to hit those targets accurately in a timely fashion. I guess I will find out next week if I am ready.
