Hi all, I’m wanting to do a dope chart for a few of my rifles. I have a Leupold CDS dialed in for my main hunting rig and seems to do very well. I’m starting this hunting season with hunting suppressed. I’m going out this weekend to see where POI is landing now that it is suppressed. I will not have time to have a new CDS dial made so I want to figure out the D.O.P.E chart. I have a limited understanding of what it takes do make one and hope that someone could spell it out for me. I do have the Applied Ballistics app, and I’m guessing I can make one from that, but I’d really like to understand it more.
Good timing on this one. I have a video coming out next week showing how to do this step-by-step.
Applied ballistics is a good app, though my personal preference is the Hornady App. You’ll need this information:
Bullet BC (on the box of ammo)
Muzzle velocity (number on the box is approximate, but if you have a chronograph it’ll be better)
Distance from the center of your barrel to the center of your scope lens
Twist rate of barrel
Environmental conditions (Altitude, pressure, temperature, humidity)
You’ll type all that info into the app and it should spit out the info you need. If you’re printing a chart, you can use the online app from Hornady and it spits out a chart that you can print. Ballistic Calculators - Hornady Manufacturing, Inc But the Hornady 4dof app is a bit better.
I have a similar problem for my muzzleloader. I can’t get my CDS dial in time. I bought some scope dial stickers on Etsy. I’ll figure out the scope clicks and then put the corresponding yardage sticker on the turret until I get my CDS.
I finally went out and sighted in with our cans and took out the Labradar, MagnetoSpeed V3 and the Kestral and got all the good data. Now I just need to figure out this Hornady app. I have everything in Appliked Ballistics but I’m not sure it can spit out something like Hornady can,
The two columns I’m working with is the Trajectory (IN) and Come Up (MOA). What I’m struggling with is the negative number in the Come Up column, to me that seems it wants me to dial down, that does not seem right to me, so I checked with my Applied Ballistics app and inputted the same data and took 300yards as a sample and sure enough it says at 300yd, to dial down 3.6moa which is down 13 clicks.
I sure would like to wrap my head around all this. One main thing I guess I’m struggling with is the turret on my scope, which to go UP it is counterclockwise, so if I do have to indeed go down 13 clicks at 300 yards then I would turn it clockwise, correct?
