I do admit though the recoil is pretty severe in 7dtd, it shouldn't jump THAT much. Then again recoil irl would be easier to deal with than in a game, Thats why alot of shooters just have the crosshair get bigger as you fire insted of physically move the gun. Guns that should have a strong recoil in 7dtd would be the ak47 if rapid firing but if firing in single/small bursts it should barely move.
Then again I rarely use guns anyway as most of them are weaker than the crossbow. Its why I like the undead legacy mod, guns actually feel like guns in that mod, and they are a direct upgrade to the xbow, even the pistol is very useful in that mod. Compared to Vanallia where other than the magnum and 7.62 ammo using guns the rest aren't worth the time. I use valmod expansion version and it has a weapon silencer, but even with that I still prefer the xbow as its just as strong, this is without using the iron or rapid xbow, or having the archery passives for 10,20 or 30% more entity dmg.
My biggest issues with most of the guns is their damage is just to low for how resource intensive the ammo is. I'm playing a insane game, 1 xbow steel bolt to the head kills half the zombies in the game in 1 shot with a headshot, but if I use a high qual pistol? takes like 4-8 shots to do the same thing. 3-4 at the minimum even for the weakest zombie. Its a balance issue.
Also you wanna see something funny? Look up Science of Stupid episodes on youtube or somewhere, they show people doing various things, and then explain how to do it right and what they are doing wrong. ALot of episodes of it involve stupid people trying to do stuff and failing majorly at doing it.
