Bullet coating?

[bruce moulds]

iaowho,
long bore riding noses can benefit from some coating of lube on the nose.
this is because the noses often bump up into the rifling and leave lead which hurts accuracy, particularly at longer ranges.
tallow or standard bullet lube are good for such use.
when you light the fire, not only do long noses bump up, but so does the bearing surface.
while good for smokeless ammo, this is why sizing bullets for bpcr being beneficial is an urban myth.
before that bullet starts to move, it is the diameter of the inside of the obturated case.
thus a mould that will cast a bullet of that diameter is optimum.
the added benefit of this is that no case sizing is necessary, and nor is a seating die,
keep safe,
bruce.
