These won't group in my .222R and are more suited to barrels with a faster twist than 1 in 14.
Got the headline slightly wrong. Should say Code 1330, Spitzer .224 50 grain.
To quote from the Sierra web site about these bullets:
22 Caliber (.224) High Velocity 50 gr. SPT
In rifles, this bullet is fully capable of producing 1/4 minute of angle accuracy at velocities that would destroy most other bullets. Each bullet has the Spitzer point shape and a flat base. This bullet is the choice of many accomplished varmint hunters. It features precisely drawn jackets to assure pinpoint accuracy and reliable expansion, even at maximum ranges. This bullet is slightly "hard" at 222 or 223 Remington velocities, but are especially well suited for velocities from 22-250 and 220 Swift cartridges.
