I guess I have to invest in a chronagraph to find out what my velocity is going to be.
The farther out of the neck your bullet is seated the lower your pressure will be, until it touches the lands then you'll see a sharp increase, maybe not a large increase though. If you know your bullets true BC all you need to do is shoot it down range at different ranges, say 100yrds zero 300yrs, 500, 600, yrds. And measure the drop to the center of each group write it down, get on a balistics program such as JBM, try different velocities until you find a velocity that match your recorded drops. Then take the money you would have spent on a chrony buy more reloading supplies and shoot more
Those down range groups say 300 and beyond, the farther the better will tell you more than a chrony can
Keep in mind the animals we shoot for food and display are not bullet proof. Contrary to popular belief, they bleed and die just like they did a hundred years ago. Being competent with a given rifle is far more important than impressive ballistics and poor shootability. High velocity misses never put a steak in the freezer.
