Here's how, size and seat 416 HE, one simple 1" die,
I do primer work separate, not in the press. SO First with lock ring set, I size cases.
When coming back out of dies with case, we notice the case still well centered,
held straight, when it is down as far as the length of the 416 HE neck.
So we put washer or another lock ring on, same thickness as neck length,
below original lock ring, screw down tight tight in press,
SEATING HEIGHT bushing or a plug goes in the top for bullet to push against.
After priming, loading in the powder charge, 2 ways then to go, one,
with tall press, carefully start(boat tail makes it easy)bullet in case by hand,
slide up in die, raise ram to to top, bullet seated., or 2 in shorter press, run case
up in press, about 4/5 the way, unscew bushing/plug, drop in bullet, put bushing in,
and raise ram, bullet seated , Cases sized so bullet is held by heavy necktension.. Ed.
