So do we.I fail plenty.
What if I have no freebore,I only did 1 pound cast and it dont look like others.My rifling starts at the case mouth and tapers like a transmission funnel.Angle is the transition between "bore" diameter (nose that rides the lands) and the body diameter, sized to slip-fit into the freebore part of the rifle's throat.
I am bad at notes,I really need to start keeping track of all things.I've learned far more from what didn't work than I ever did from what worked. I keep the most complete notes as I can on all loads and most certainly including what didn't work.
