Hi Guys, I have a Panthera 700mm .25 FAC , it is under powered, using 34gr H&N slugs Reg pressure set @ 130 bar, and the power wheel on 23 with quick tune on 4 I am only getting 750fps, the Brother of my friend has the Identical rifle and with the same setting it is doing 1020fps.
I have checked the breech seal etc, but that is fine, the other thing is when adjusting the power wheel from minimum to maximum there is only about 30 fps difference, Any ideas of what to check next?
TIA
