Convert Power Guns to Fire HMG Bullet Projectiles

[linehand]

Heavy Machine Guns actually fire bullet projectiles, like Smart Guns, but without the smart targetting/tracking. All Power Guns should behave like HMGs in this regard, so that they actually have physical bullet projectiles in the world, rather than behaving as unrealistic hitscan guns. This would have a major impact on general immersion, especially given that time dilation mechanics are a part of the game.
