Their test string varied between 800-820 fps with 8-grain pellets. Tech felt it would be tighter with JSB 8.4-grain pellets or 7.9-grain pellets. The string started at 805 fps. Once the velocity dropped below 800, they stopped the testing. The test was started with a 200-bar fill. Around 150 bar, the velocity was still pretty consistent. Each gun will be different, so your mileage will vary.
