ExactlyThere's a difference between a 10.3 in 177 and a 14.66 in 22. The 14.66 is not a heavy for caliber pellet so it doesn't hurt the gun. Over 16 grains is when 22s become heavy for caliber. It has to do with start pressure. Not actual weight. 22 has more surface area and has a lower start pressure. It's why they are generally more efficient and smoother than the same platform in 177. Keep shooting the FTT in your 22 Hw30s. It's totally fine. I wouldn't go any heavier though.
