I don’t know that much about it so I might be missing something but it seems like the losses would be worse than what would be gained from doing this. The barrel is already short so efficient powder burn is going to be minimal as is(and I would assume lessened by the porting) and I also assume that putting holes in a barrel that short would be a detriment to accuracy. The only positive I can fathom is that it might reduce recoil.
Why not just get a threaded barrel and put a muzzle brake on though?

If a person with no formal education can make a functional firearm in the middle of the jungle out of basic materials than just about anyone with half a brain in a first world country can as well.
Berezino Beach Assault with CRTI
At around 5:42 I unload a 10/22(or Sporter 22 as it’s called in DayZ) with a BX-25 magazine into the chest of a naked guy who I believed to be doing recon for the enemy.
