Shooters have made comparisons to the Ghost likely because they share the same power wheel, or maybe because they are mechanical which is unusual for Daystate these days? I don't know. What I did notice is that I have a Ghost HP in .177, and using the same 10.3 gn JSB's the BW perform better velocity wise. The ghost is set at a reg pressure of 105, the BW at 100. The ghost has a 23" barrel as opposed to the 17" on the BW. The SD is 2, or less as they sit, yet the ghost velocity is 917 as opposed to 975 on the Black Wolf. Not sure if this means anything as the Black Wolf has about fifty pellets though it, but some may find it interesting. Just something I noticed.
