My 22 syn-rod loves the H&N Barracuda Match 21.14 domed pellets the best and will stack pellet on pellet at 25 yards. It will shoot the CHP 14.3, but not as accurately as the H&N's. I was told by a friend that works at crosman that their 22 barrels like the 5.53 size pellets and he was 100% right. I tried the H&N FTT in 14 gr weight with the 5.53 head size, but they weren't any better the crosman pellets. Going to stock up on the barracuda match for sure.
