603, try a bushing one size larger in the die so there'll be less neck tension; too much neck tension will hurt accuracy and sometimes ends up bending the case neck at its junction with the shoulder. One that's .001" smaller than a loaded round's neck diameter may make the most accurate ammo.

Then seat bullets out to where the just barely set back a few thousandths when chambered. That'll center them very well and help uniform startup resistance so velocity will be more consistant.

Good to see you fixed some mistakes. There's a few dozen I've made over the years. Finding and fixing 'em makes one smarter. . .if we remember them.
