All barrels are different, the FX hybrid .25 were pretty damn poor in my FAC.

In my .22 the standard JSB Exact jumbo 16gn is very good but the Express & RS less so, the heavy 18gn & monster 25gn are frankly cr*p.

But regardless of that, My question was "Has anyone tried the pro-hunter slug ?"
I wasn't asking for a debate on the best .22pellet
