@lowlight
You talked about trueing (BC vs MV). and using JBM to back calculate from real data.

I want to get back to using range cards and drop charts in the field and rely less of electronics, so I recently purchased Coldbore (desktop). I'm a CB rookie and wondering what's your process for trueing ballistics is CB ?

Same as every other place,

get my 800 yard drop and adjust based on that

Ok, being new to CB, wasnt sure if you'd true BC or play with drag coefficient. And whether you used JBM to back calculate (or if there were tools in CB, like there is for "true zero range")
Thanks.

Don't use the Drag Coefficient

that is a very specific tool
