Hi Guy's. I recently had my .25 sent into get a Suppressor here in Nz. I left it up to the gunsmith to decide how much to cut the barrel down.... Came back pretty short! Now at 18.5 inches without suppressor and 22 inches with it on. Now by most accounts this is rather short for a .25 which like the slow burning powders. It is blowing power out the end into the suppressor but still pretty accurate. I am going to load up some of my own ammo and am guessing I should try slightly faster burning stuff? Any pointers / idea's would be appreciated. I have some IMR 4350 which seems to be quite popular for the .25's? Many Thank's - George.
