I bought the Panthera Slug Power kit and installed the hammer on my .22 Cal, but I'm hesitated to install the pin probe because I'm worried the pin probe won't push the slug deep enough past the transfer port or even to the liner, because it really depends on the slug end shape, if it's flat base, the pin probe should push the slug to the same depth as the stock probe does, correct? But if it's dish base, it won't get as deep as flat base? Do anyone get consistent result from installing the pin probe? I have a lot of Javlin 34gr and 40 gr for my Panthera .22 Cal 600mm, do you recommend me to install the pin probe? If so, how many fps will I gain by that? Thanks a lot!
