Load help

[wow6599]

Anyone have any load data on these -

Berry's 180 gr plated hp for 10mm and Berry's 9mm 124 gr plated hp using Unique powder.
Somebody gave me 1lb of Unique, which I've never used before, and all I have is info on plated bullets using AA.
I can come up with a ballpark number on weights, but not length. I always prefer solid numbers if they're out there.

Go to http://www.alliantpowder.com/ find and download the free reloading manual in PDF format or use the interactive data.

Reduce the maximum load data listed for the same weight Gold Dots by 20% for your start load using lead or plated bullets and work up to no more than a 10% reduction as your maximum load. Lead and plated bullets have less resistance in the bore so they will shoot at higher velocities than a jacketed or in this case a thick plated jacketed bullet.

Its been my experience that a jacketed start load (-10%) will push a lead bullet at the same velocity as the maximum jacketed bullet load will push a jacketed bullet hence the 20% reduction of jacketed data for lead and plated and maximized at a 10% reduction.
