Guide reports incorrect compatability with ammo types.

Found in the BN discord:

My rough guess is, note how it shows some 5.45x39mm and 45-70 guns in there. It's likely searching for the string 45 in ammo_type and picking up some hits of the wrong type, because 545x39 and 4570 contain the string being searched for.

What really throws me for a loop is, why does this bug cause the the two AKs and the gatling gun to mistakenly show up on the list, but not the three other .45-70 guns in the file...
