I made a bolt action rifle that works as described: https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=1380273256

For a bolt-action rifle like the K98k you could make it so that the charging animation is the bolt being cycled (for like 0.6 seconds), during that time you can set a charge level with a projectile count or damage of 0 (when fired too early it simply wouldn't shoot a bullet/ do no damage), after the animation is through it would be in its fully charged state and fire upon releasing the trigger.

Oh wow, thanks! It's a shame u can't balance it's stats properly but it's still very cool!

I've just uploaded my animated Glock 19: https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=1379820150
Basically, what you do is you make a charge gun that is instantly at full damage potential and where the "uncharged" look is the same as the "fully charged" one. But instead of making the firing animation a single frame with muzzleflash like the original Charge Gun uses, you make it multiple frames of the weapon cycling. The only problem that comes with this is the fact that the gun can be fired as fast as one can pull the trigger, which can lead to an immense dps, and that fully automatic firearms aren't possible (the gun fires not upon pulling the trigger, but instead when you release it).
If you want to try it, feel free to download and unpack my mod to see its inner works. It's really quite simple once you've figured it out.

It is possible to animate (based on the charge gun's mechanic), but I don't have time to explain right now.

It doesn't require anything.
Bolt is not animated, idk if it's even possible in vannila starbound.
