sorry swampman after reading my last post last night . my comment seems alittle curt .

for those without charts , the math isnt hard to do
Determine the volume of a sphere: Diameter cubed (D x D x D)X.5236 X 2,873.5
(2,873.5 is the weight of a cubic inch of pure Pb in grains).
the result is the wieght in grains of your soft lead RB

so lest plug in a .440 RB and see

.440x.440x.440 =.085184
.085184 X.5236 = .0446023
.0446023 X2873.5 = 128.1647
so the grain wieght of a .440 pure lead RB is 128 grains

if it doesnt wieght that . then
1) you have a void in your ball
2) your ball isnt made of Pure lead
3) your scale is off or been zeroed for something and is deducting some wieght

or you can go here and use the calculator
as you can see the lightest is Linotype at 118 grains
