Lee Perfect Powder Measure Trouble

[Tsm002]

I just got a Lee Perfect Powder measure, and I'm having a REALLY hard time wfiguring out how to use it. I know it sounds dumb, but I wanted to check with the folks here before I go any further.
How do I set the little micrometer thing?
I want to load .38 special and .357 magnum cases with 2.7 grains of bullseye for wadcutter loads (148 grn plated HBWC). WHat setting do I put the micrometer on? It's in cubic centimeters, and I want to double check my math before I start throwing powder charges. I'm really worried about either setting it too high or too low and getting a problem with that.
ANyone else here use the perfect powder measure with bullseye? If so, what is your setting for 2.7 grains of bullseye?

There is a formula that comes with it, but just measure out and adjust the charge and weight until correct weight found.

Never, I say again, never, use a powder measure without having a powder scale to check it against...

Just a friendly reminder...

as all have staed above. I don't see how they could give you a specific setting
for a specific powder, too many variables.

But you could document your settings with specific powders but I would still check, as I do, after so many rounds, say 15 rounds throw and weigh the charge to see if it is the same. I know as my powder holder gets less and less powder in it the charge weight changes.

Allrighty. I will invest in a powder scale-what's a good, inexpensive model?

Although I prefer the RCBS scale, I used the relatively inexpensive Lee scale for quite awhile with no problems.

The Lee kicks ass and is cheap.

What more do you want?

Midway is advertizing an electronic scale for $30 or so. Cannot tell you if it's any good. The cheap one I bought 6 years ago (different brand) works OK, and I always make sure I check it against a known weight before I start.

The lee scale is incredibly accurate, only problem I have with it is that it only handles 110 grains or less. For under $20 there isn't much to complain about.

I am throwing RL15 for highpower 223 (23.8g) and get within +/-.2 (usually even better but wanted to say worst case). My only complaint is the hopper is a small, I reload once the hopper goes down about 1/4 to keep things consistent. Have had good luck with IMR 4895 too.....but don't expect miricles with IMR 4064 (that stuff is just too long).

I have the habit that, once the hopper gets down to about 1/3 full, I fill it again - doing that has always given me consistent measurements by test.

yes sir....good idea. I do that also when it is about 2/3 empty:D

The Lee Perfect should have come with a chart. This chart shows the "VMD" factor for various powders. This factor is the approximate weight in grains per cubic centimeter for a listed powder. Looking on my powder shelf, you will see these factors written in sharpie on cans of powder. For example, if a powder's VMD was '.741' and you wanted to throw seven grains, then 7 x .741 = 5.187. Set the barrel on the measure to about "5" and then throw a few charges, weighing each one. Throw till they are uniform, adjust, repeat until you are throwing what you want consistently.

If your did not come with a chart, I would guess that it is available on line. If not, PM me and I will arrange to copy mine and sent it to you.

Since it is so very important, i will repeat the advice, with all respect.

DO NOT reload without a scale. I prefer a balance scale. Others prefer en electronic. Get what you like, both, but not "niether".
