0.18 sniper ammo does not get damage upgrades.
SchallAmmoTurrets_0.18.1
Also turret itself does not seem to get upgraded damage.

Huh? Really?
The ammo and turret both work perfectly fine on my side.

Check the numbers in your game if it is very different from my screenshot. If so, show me your screenshot too. You can upload to file host just like ImgBB.

Must be krastorio2 or space exploration interfering probably.
I'm guessing krastorio2 interfere with sniper turret and sniper ammo upgrades. Because other turrets seem to be getting upgrades.

If this is the case, I am not going to do anything specific to this.
It is because every overhaul mods are making tons of changes to vanilla items and techs (that's why they are called "overhaul"), and do it in very different ways. It is not possible to adapt to all these very different ways. I do not have lots of time and energy for them.

Fair enough.

狙击炮塔并没有像原来一样射击的射击模式，现在一个敌人会被很多狙击炮塔命中。会浪费很多弹药，并且让狙击炮塔显得很鸡肋。几乎完全没有防御能力，怎么回到之前的版本？

之前版本的狙击炮塔射程最长却无延迟，过强了，其它射程较短的炮塔变得没用处了。而且狙击炮塔使用的弹药也算最便宜的，性价比也远比其它的高。玩家只用猛堆狙击炮塔就行，这太影响游戏平衡了。
现实点来说，狙击也需瞄准时间。
狙击炮塔的瞄准/延迟时间 (warmup time) 倒是可以调整，目前设定为一秒。但坦白说，真人狙击手从举枪到按下板机只用一秒，已经很快吧？

我鼓励防御建设多元化的，敌人跑得太快、无防御能力的问题，可以配合「重机枪炮塔」或「火焰炮塔 - 丙烷」等中短程而火力强大的炮塔。另一种玩法则是配合《疾风异星科技》(Schall Alien Tech) 内的「静止束炮塔」或「原力炮塔」将敌人定住。
狙击炮塔无延迟的话，玩家无脑堆狙击炮塔就能杀死所有敌人，这样一点也不好玩。
