i have seen similar effects in other games (shooter, etc). In 90% of cases it helped me to just center all axis, throttle, sliders... Maybe you should check this.

Maybe you should ask at PzBtl911. There are at least two guys, who served as recon soldiers. Ask for "Aufklärer" (served on Leopard1) and "Sturmtiger (he was on Luchs). And "Abraxas" was a former Batallioncommander, but I don´t know if he was in an recon btl.
don´t forget to reset the counter after reloading and before you set the value. Do you see the little green counter? This counter is directly affected by AMM UP/DOWN. Then the store button saves this value into the normal ammo counter.
you have to deactivate the palmswitch by holding [P] on your keybord while clicking on F3 this is not the way, how it should be done. First you have to activate "load pos" as I mentioned above. Then a little green counter appears above the normal counter. This green counter can be set with the "AMM UP/"AMM DOWN" buttons. Then you can store the value.
