more like unintended feature to be honest

I took my lvl 45, put machine gun/sustained fire and put all points into ammo recovery.
Put 2 rare mags in the slot
+45 x3.50 = 158 ammo/min

No idea how to resolve this but I think creating legendary ammo out of hopes and dreams might need a lil nerf somehow.

Hello!

ahaha thanks for the feedback, I know ammo recovery is a bit OP right now, I'm not sure how to properly address it.
I think I'll be trying to implement it in the "ammo saving" aspect instead of regeneration, this might mitigate the strength of the perk while keeping it interesting

I don't think a % chance not to consume ammo as that is quite boring, perhaps every x shots get a free bullet? Productivity for bullet shots.
That way it can stack to the point you get 2 bullets for every one shot.

Ah, that's a great approach. I like the "productivy for bullet shots" pattern since it re-uses the design language of vanilla Factorio, thanks for your input!
I'll try to have that changed in an upcoming release :)

Another issue you might face is how much to increment with each point. Because depending on what you're shooting you might as well but the point into damage.
Let's say %5 per point in "bullet prod", needing 10 points for 50% prod feels pretty good but I think playtesting to see what feels good will be needed to make sure
And replacing the +X ammo/min with the magenta prod progress bar we're all familiar with along with the actual prod% right of the bar should be perfect for readability

This is now implemented in the 0.10.4 release
