Fix scoped K43 and Garand recoil to 71 FPS physics

[x0rnn]

Currently the recoil is between 71-125 FPS as per #1680. I'd argue this is a major nerf for those who were experienced snipers, whereas it changes nothing for the average sniper who always used 125 FPS.

Making the recoil equal to 71 FPS physics would make both experienced snipers as well as average/beginners happy/happier and improve their sniping.

In short, currently it's a major nerf and nobody is happy, making it 71 would make everyone happy and buff the weapon for noobs a bit.
