I bought some Lee 380 ACP dies. The instructions say "It is dangerous to use a bullet of greater weigh with a charge for a lighter bullet. Never select a load intended for a bullet lighter than you are using. Loads for a slighter heavier bullet are safe." But it seems it would be the other way around.
What is the rational?

EddyQ,
welcome to the forum.
Lee's instructions make sense to me.
Why would you think that? just curious.Originally Posted by EddyQ

Lighter bullet = more powder.

With a given charge of powder a heavier projectile makes more pressure than a lighter weight one.
Welcome aboard.
Because it would seem that with bullet of greater weight you would want a greater charge. Or for a lighter bullet you would want a lighter charge.
No, proper as stated, the heavy bullet with the charge designated for a lighter bullet may
cause pressure issues
Do not confuse bullet weight and charge weight in that statement

Oh, then a charge for a lighter bullet would be more charge since the pressure would still be acceptable? The reason I asked this question is because I was also loading 7mm Mag 150g bullet but could not find load data for Nosler 150g and used the charge for a 160g bullet. So that was a lighter bullet with a heaver charge. And according to the LEE statement that would be ok?
Perhaps ok, guns are like women, each is different
each bullet style has a different curve (ogive), toughness, etc.
but good ball park logic
Go here and look up loads

They list the 150 gr Nosler

Welcome aboard, there are numerous online sources for load data so it pays to do a little research first.

maybe you didn't look very hard?
I'd go to Nosler first.

I hope you know the full name of your 7mm Mag cartridge ...cause they don't list 7mm Mag

That is one of the sites I searched but they only list hodgdon powder. Maybe I should start a different thread because my original question suggested I was looking at 380 ACP and this question is now about 7MM Mag.Perhaps ok, guns are like women, each is different

OK, what powder were you wanting to load in the 7 Mag?

Not meant to be offensive, but for a newer reloader (I determined this from the original question), just stick to what's in your manuals, and in time, with more understanding of charges/pressures you can "extrapolate" charges. As mention/explained above, a heavier bullet using a lighter bullet's suggested powder charge will generate more pressure (is it easier to push a Volkswagen or a Cadillac?). Find a load in your manuals before you purchase any components. This will eliminate most headaches and waiting. If a specific bullet/charge is not in a manual, there just may be a good reason...

You didn't read the question. I was very clear that I wanted to understand the rational behind LEE's statement and that was answered above.
When you go over to Alliant's Load Data site , Alliant makes Reloader 22 , you will see the following six rounds listed under 7mm Magnum.
7mm Short Action Ultra Magnum
7mm Remington Magnum
7mm Winchester Short Magnum
7mm Weatherby Magnum
7mm Shooting Times Western ( it doesn't say magnum )
7mm Remington Ultra Magnum
The 7mm Remington Magnum and 7mm Remington Ultra Magnum are the two most confused.
Make certain what the caliber of your rifle is and make sure your loading dies are correct . When you say 7mm Magnum ...there is none.
Under the 7mm Remingyon Magnum Alliant only listed load data for RL26.
These pesky details do make a difference.....load safe !

I read your post a couple times (a basic "Reloading 101" type question), and my post referred to the answers offered in several posts ahead of mine. I just added some pertinent info so a new, inexperienced reloader could understand, and a hint to keep one out of this kind of trouble.
Have you any reloading texts/manuals besides the Lee die instruction sheet?

It's not a bad idea to look for multiple sources for load data, to cross check it - If one manual has a typo and you trust it, you could get a "Kaboom", and NONE of us wants that. I cross-compare and start with the lower starting load, and usually use a slower powder for the longer barreled rifles etc.
The heavier the bullet the less powder. It's a common mathematical formula of mass, force and volume. Please read Richard lee modern reloading manual #2. Or find a seasoned mentor. Be safe and carry on.
If you have it, read it, if you don't have it get it, the Lyman Handloaders book, it is one of the best.
Take the lee instructions and use them to start a camp fire.
