So this ammo fps might be calculated in a 24" barrel. If it is then a 20" barrel will probably yield about 2740 fps. So at 2740 at 100 yards your looking at a 2.62" drop if you have a 25 yard zero. So when all is said and done you need a 2.62" up on a 25 yard target to hit a bullseye or close it it at 100 yards.
We have to remember bullets starts dropping the minute it leaves the barrel almost. Gravity has a way to do that to us or else we would be floating around or have had the ability to fly haha!
