Find out which launcher is right for YOU! Take the quiz here:
The term Caliber refers to the diameter, or size, of the projectile, and is generally expressed as hundredths of an inch. So when you see .68 caliber and .61 caliber, we’re talking about two different projectile sizes.
And here’s the important part: they are not interchangeable.
If you have a .68 caliber Byrna launcher like the SD or LE, you need .68 caliber projectiles. If you have a .61 caliber launcher, like the Byrna CL or CL-XL, you need .61 caliber projectiles. Buying the wrong size is like trying to put triple A batteries in your TV remote that takes double A’s. They may fit but you’re still going to wonder why the TV isn’t turning on.
Now, a lot of people see .61 caliber and think, “Wait, if it’s smaller, does that mean it’s weaker?”
Not at all.
The .61 caliber projectile may be smaller, but the launchers that use it are designed to fire those rounds much faster. Byrna’s .61 caliber CL platform fires projectiles at speeds over 400 feet per second, compared to many of the larger .68 caliber launchers that are closer to the 300 feet-per-second range.
So the takeaway here is simple: don’t shop by guessing, and don’t mix calibers. Choose your launcher that best fits your needs, and then make sure the projectiles you buy match that launcher’s caliber. If you wondering what launcher is right for you, take the quiz at the link found in the description to find out.
That’s it for today’s lesson. So what are those burning Byrna questions that YOU have? Let us know so that we can make sure that we’re all prepared to defend.
