Hi all.
having been out of the fx impact scene for the last 18 months, i am thinking of getting a .25 cal FX impact M4 in 700mm, this would mirror what i used to own when i had a M3 in .25 cal ,my question is will my old tune for shooting 41g slugs at 960fps( sub moa @100 yards), get me somewhere in the same ballpark with this new M4? my old M3 was a stock rifle with no internal mods, obviously the M4 uses the one reg but that is the only difference, i intend to keep everything on the new M4 pretty much the same.
old M3 tune - front reg 175bar-rear reg 155 bar- macro 16- micro 4.75-valve 14mm off the block.
