I have three boxes of 500 Rounds of Remington Viper 22lr Hyper Velocity Ammo 22 lr 36 grain Copper Plated Truncated Cone Solid bullet 1410 fps. Each brick contains 10 boxes of 50 rounds $60.00 per box. 1410 FPS Hyper Velocity- 155 FPS faster than "High Velocity" cartridges- for flatter trajectory Tuncated Cone contour for higher retained velocity and energy at longer ranges. Solid Bullet Construction for accuracy and "Hyperformance" on small game. Copper-Loct bullet plating for easy feeding and chambering with reduced barrel fouling. Thanks for looking.
