- The 45 gr bullet weight and 1090 fps muzzle velocity reflect a specific performance profile, so it is worth matching to your firearm and intended use before buying in volume.
- This is a .22 LR cartridge, so it is intended for rimfire platforms chambered for that caliber only.
- Packaged as 100 rounds per box and 20 boxes per case, which may be more than some shooters need for occasional range use.
