Tuning Edgun R3M Long

Hello Guys

Does anyone knows if it's possible to modify Edgun R3m .25 long to push 3 gram slug 900 or > fps?

Shouldnt be hard... Some porting job and ditching regulator or making regulated volume bigger should do the trick.. 112joules at 25cal isnt really that much to ask.. Im not familiar what twistrate R3m has but be noted you need 1:18 as minium to get stability out from such slugs preferably bit faster.
