Can anyone tell me the POI's for a 16"; 1:9 for the following?

Zeroed for 200 yds = POI @ 100
Zeroed for 300 yds = POI @ 100
Zeroed for 400 yds = POI @ 100
Zeroed for 500 yds = POI @ 100

Thanks,
Mickey

Use this:

To get your weight and velocity and use here to check your trajectories, or similar place.
internet.cybermesa.com/~jbm/ballistics/traj_basic/traj_basic.html


I used BC for 55grn at 0.272 and velocity of 3162 from table (should have been 3132, duuhh, I forgot) to get these figures, plug in your own numbers for yourself:

Uh okie dokie. I guess that takes care of that! Now I have to take off my shoes so I can do the math! LOL. Thanks Halfcocked and Mike! Now I can figure out the info I need for any/all bullet/barrel combinations!


Thanks again!
