Assuming by "Dope" you mean coming up with data to input into a ballistic software model...
Its true that entering accurate numbers will give you better results. Garbage in,garbage out. Do your best.
Get as close as you can. Ballistic software can be remarkably accurate.
But you will have other variables. Advertised ballistic coefficient is a big one.
Advertised BC sells bullets. And,in fairness,technology has improved. There are updates to the numbers.
Subject to your engraved rifling,twist,etc the true,effective BC of your bullet fired from your rifle can vary from the spec printed on the box as much as velocity of factory loads
The air varies every day.
I'm an advocate for using ballistic software. It rearranges how we think . Gets us on target quick.
It works remarkably well.
But you still need to upgrade your "Dope" by going to the range and shooting. Discover and record those few clicks correction at various ranges.
Hopefully accurately lasered ranges. As you gather these data points, you can use them to redefine and correct the ballistic curve your software creates.
Thats next level.
