Painless load development (mine)

[Carl Ross]

As a relative newbie to the long range game, is there a thread that focus on truing at long range? Im assuming the best method is putting paper out as far as possible and verifying your impact, but after that i get lost. Do you then fiddle with your BC until your dope chart matches the actual results? Something else? Don't want to hijack this thread so any links to relevant threads are welcome.

If I have a GOOD chrono (Garmin, Labradar, Magnetospeed, Ohler) I trust the velocity and true the BC. If you have to move a CDM more than a few percent, I'd double check the rest of your inputs, they're usually pretty good.

If I'm not using one of the chrono's listed above, I trust the BC and true the velocity.

Yeah, I have a Garmin, and this is exactly the point where I've gotten confused. I've heard both before - true the velocity vs true the bc. I could never understand truing the velocity when I have actual hard data from my rifle, whereas BCs are published and I've heard on more than one occasion inflated.

Over hunting distances as long as you are truing it probably doesn’t matter, however the ballistic aps make it easier to use the velocity solution.
It’s also far more common to get accurate BCs now than in the past.
