Manufacturer – CCI
Bullets – 40 grain lead round nose
Casings – Rimfire-primed brass
CCI enjoys considerable clout as a premier manufacturer of rimfire ammunition. If you have ever fired a weapon chambered in .22lr, chances are decent that you did so using CCI in one form or another. CCI’s 22 long rifle ammo is probably the most common “first timer” ammunition out there on the market today. It’s reliable, relatively cheap and made right here in the United States.
While CCI does manufacture a host of centerfire offerings, as well as reloading accessories and parts, rimfire ammunition has been their mainstay with a broad offering of different loads for different applications.
The 40-grain lead round nose (LRN) is the SUV of rimfire ammo. It is not exactly match grade, and it is not designed specifically for dispatching varmints. What it is really good at is buying in bulk and allowing a novice shooter to learn the trade and become an experience shooter, and 5,000 rounds will dispatch a whole lot of tin cans.
Muzzle velocity for the 40 grain LRN is listed at 1,076 fps at the muzzle and stays fairly consistent out to 100 yards where is clocks in at around 900 feet per second.
The standard zero for a rimfire rifle is 50 yards, so at 25 yards the 40 grain LRN will shoot slightly high. After the 50 yard zero, it advertises a drop of -2.6 at 75 yards, and -7.6 at 100 yards.
