Hagar,

It doesn't usually cover the whole bullet. They just painted a stripe or two inside each neck to act sort of like O-rings. Bullets still get stuck hard if the ammo gets old enough. Normal pull weight is well under 100 lbs, but a former Aberdeen Proving Grounds employee said he'd measured up to 600 lbs pull in some old stock. Still fired properly, though.
