My HW97 loves Heavies but I’ve read on another forum that they may reduce spring life. I did break a spring after 3-4000 shots and getting the replacement spring to produce the same 13.5fpe is such a pita that I switched to 8.4s. Accuracy is still fantastic. Love this gun! Uj
Always use the pellet the barrel likes. Doesn't matter what they weigh. I have many 12ftpd guns. Half of them only like the 10.34 heavies. Other ones like the 8.4s. I have also tried the jsb 13 grain in a couple of them. The heavy pellets have more energy down range anyway.
I have been trying to find a pellet that my Daystate likes for shooting Metallic Silhouette at 30,36,40 & 45 yards any suggestions for one pellet for all yardage.
