Retailer records identify this Lake City package as SG223KW with UPC 020892233379. No current Winchester product page or exact manufacturer ballistic table was verified for this SKU, so data from USA223R1 is not transferred.
Key Takeaway
Winchester SG223KW is a distinct Lake City 223 Remington 55-grain FMJ package. It should not be merged with USA White Box USA223R1 because the verified product codes and UPCs differ.
Official Ballistics
No exact current Winchester ballistic table was verified for SKU SG223KW. Values from the similar USA223R1 load are not substituted, and no wind-drift or trajectory table is calculated.
Bullet and Load Design
The 55-grain full-metal-jacket bullet is configured for range use and reliable feeding rather than controlled expansion. The SG223KW product identity is kept separate from other Winchester 55-grain FMJ packages.
Best Uses
This load is best suited to target shooting, training, and general range practice. It is not presented as an expanding hunting or defensive load.
Reliability Notes
Retail availability and packaging do not establish function in every rifle. Confirm feeding, cycling, accuracy, and point of impact with the individual firearm and magazine.
