I am shooting 162gr A-Max bullets, the last time out I shot 4 shots at 200 yards and a quarter would have covered all 4 shots. So when shooting the extended distances should a person re-adjust their scope or take a mental note and where your hitting, say at 400 yards the first dot down from the cross hair its shooting low and to the left, make a mental note of that or adjust for it????
I will also tell you I am not impressed with the sightron scope for longer distances, but can't afford anything else. Thank you for any advice.
Chuck your bullet is falling to the ground at the speed of gravity fom the moment it leaves the muzzle.
If you are zeroed at 200 that zero is good only for 200yds.
I plugged this into Hornady's ballistic calculator to give you and example.
200yds zero, Amax 162, 3000fps.
To compensate for the drops you either hold over the target they appropriate amount, or you adjust the elevation on your scope to match. If your scope adjustment is a true 1/4 MOA per click, then you come up 4 clicks per MOA of adjustment needed. Again using the same calculations.
100yds=-1.3(hold low about 1.3")
200yds=+/-0 (hold dead on)
300yds= up +2.0 MOA or 8 clicks
400yds= up +4.2MOA or 18 clicks
and on and on out to 1000yds where your come up is 23.0 MOA or 92 clicks.
Now if your elevation turrett is a target or tactical turrett that shows MOA it's really simple.
If you don't have those types of turrets then the best advice is to practice noting how many dots you elevate on your mil dot reticle for each hundred yard increment.
