| I've seen numerous posts where people reported inconsistent powder throws when they were low on powder. As I see it, a powder baffle takes the weight of all of the powder in the hopper and supports it, so the measure itself only sees about 1/8 of the load. Is this not the same as running while low on powder? How does this make throws more consistent? |

Because it makes the ENTIRE COLUMN OF POWDER in the powder measure weigh like it's only 1/8 of the load. You will only throw light loads if the powder level goes below the baffle. |

Without a baffle, the entire column of powder is weighing down upon the entry to your volumentric measure. As the column drops, that force changes.
With a baffle, the baffle supports most of the column, and creates the equivalent of a smaller column underneath. The weight of that column stays much more even as you use up the powder in the hopper. |

...make throws more consistent? Look around for the threads about polishing and waxing the bowl of the powder thrower. Link to Google images about topic. |

Quoted: Well crap, now that I understand how they're supposed to work, I want to make one. From the tacked "useful threads" thread, AeroE's how to make a powder baffle. http://www.ar15.com/forums/t_6_42/296102_.html I followed his instructions, mine came out fine. |
Don't know. These guys talked me into getting one so I put it in there and think oh yeah it's better now !!!
I really never had any problem with my Uniflow (I have both of the drums) but the baffle really is one of those "what the heck why not" items for all of the reasons posted by the others. |

You don't need to have problems to benefit from something like a powder baffle. Dean Grinnell recommended using a baffle in "The ABCs of Reloading" (many editions ago) and I just followed his advice It works. |

Bringing this one back to life. This thread got me thinking so I decided to make one in my spare time at work. While searching I found this little gem: http://www.shootersforum.com/handloading-equipment/34885-you-baffled.html click on the pdf for complete instructions including idiot-proof cutouts. BTW: the author allows you to use this for your personal use ETA: I put my baffles to use and immediately noticed that my throws dropped .2gr with 2400 powder and were .1gr heavier with Bullseye. So be sure to check your powder throws after you install the baffle (I'm sure you knew that already though  ). |
