Lot of good stuff here, now some tips, mount your presses on 3/4" particle board or plywood, and then you can C clamp it to the table, next with a single stage press, do it in batches, clean cases, don't deprime 1st as you have to dig out the media from the primer hole, now resize and deprime, and on once fired rifle brass, meant for accuracy, deburr the flash hole, from the inside out, Now if you have adjusted your resizer, to just neck size ( for accuracy ) of have small based resized for Semi auto firing, both have their place, the place the appropriate amount of powder and seat the bullet to the correct overall length, take a little time with this as this is where accuracy really begins to start. Neck crimp is a personal decision also, if you cannot push the bullet back, against the bench by hard hand pressure, then you don't need t further crimp it further, however if it does move farther down the case, you do need to.
To be continued and best of luck.
