The Servo can only move 1 degree at a time, while the stepper motor can micro step a fraction of a degree
(like up to 1/256th of a degree).
Distance * tan (degree * π/180 )Moving the servo 1 degree will move the point of aim 2.09 inch at 10feet.
While a high res pwm into a stepper could microstep 1/256 degrees giving you 0.0072 inch movement at 10ft
something like this will work to move 15lbs at a point blank. (21ft/inch torque) 1.9A at 5V maxhttps://www.amazon.com/ANNIMOS-Digital-Waterproof-Crawler-Control/dp/B07GK1G5FV/ref=sr_1_17?keywords=metal+gear+servo&qid=1555433131&s=gateway&sr=8-17
Pins 6,7,8 9 on the Duo have high res 10bit PWM output, which will let you run a single Stepper motor at 1/256 degree steps, However, the current provided by the Arduino Due will not be enough to run the servos.
You will probably need an external control / power board like this : https://www.adafruit.com/product/815?gclid=EAIaIQobChMIw62z04vV4QIVnbrACh35pQzWEAQYASABEgIBf_D_BwE with a 5A 6V Max,
this pwm board can be used as a motor controller that could handle two of the previously mentioned Servo's. You will need to solder on the extra cap for high power. I personally use this PWM board for every project I can because of how easy it is.
