I see Paul Mays remains as confused as ever. "Weight" in this context
is mass. One clue is that not everybody measures this "weight" in
pounds; those who don't invariably measure it in kilograms, never in
newtons. The second is that 1 lb = 0.45359237 kg, exactly, by
definition.
I see that Gene continues to have reading comprehension issues.....
Since you *declared* that you were using the term "pound" to refer to
weight, i don't see a problem with your statement.
Since Gene missed that obvious point, I suggest he clean the foreign
substances off his monitor so he can read the entire text of the post.

That's being the case I added a little smiley face to show
a point of comic relief.....
I had dropped him into my killfile long ago for the simple reason that his
rantings were repetitious and no longer funny.
Another clue is that the "weight" of the bullet and the powder in this
situation is also measured in units of mass, in either troy grains or
in drams. And the troy "units of weight," unlike their avoirdupois
cousins and unlike grams and kilograms, have never spawned a unit of
force of the same name; they are always units of mass.
And Gene builds another straw man. I do not recall you discussing the
weight or the mass of the powder or the bullets.

Practice, E 380-79, ASTM 1979.
3.4.1.4 The use of the same name for units of force
and mass causes confusion. When the non-SI units are
used, a distinction should be made between force and
mass, for example, lbf to denote force in gravimetric
engineering units and lb for mass.
And since you *did* specify weight units, this reference is moot.
I built a gadget, that by placing a few ounces
of finger pressure I put little holes in paper
at 50 Yards... If it works and it looks good
all the details are secondary.......
Now I expect him to try to take you to task for "ounces of finger pressure."
