When should I use 5.51mm .22 pellets? If your .22 rifle is showing inconsistent groups with standard ammunition, the 5.51mm head size provides a slightly snugger fit that can stabilize the pellet more effectively.
-
Does a larger head size increase power? By creating a better seal in the barrel, a 5.51mm pellet can often maximize the air pressure behind it, sometimes resulting in a slight increase in muzzle energy (Ft/Lbs).
-
Are JSB Jumbo pellets lead-free? No, these are high-quality soft lead pellets. The soft lead allows the skirt to expand upon firing, perfectly conforming to your rifle's unique rifling.
