carverelliBenchmark loads for .223?
Anyone find good results using this new powder. Supposedly its more temp stable than H335. Although it won't meter as well through my Dillon, I think it will be within .3 grain. I'll experiment with both Sat by putting rounds of ammo in an ice chest before I shoot them and then for heat just leave them on the dash of my truck w/ the defrost on for 15 min or so. I'll post results when I'm done. Should be interesting

<Deafdog>Hi Carverelli
Bench Mark 1 and Bench Mark 2 are made in Australia for Hodgson by ADI.
ADI powders are very temperature stable.
"ADI rifle powders are designed to give less ballistic variation with temperature changes than regular smokeless powders."

Gary THey guys, Here's an interesting table
![[Wink]](images/icons/wink.gif)
at the ADI site that shows "powder equivalents" for various companies, including ADI, AA, Hodgdon, Dupont, Winchester, Vectan, and Alliant. Hodgdon "Benchmark" looks to be pretty comparable to ADI "Benchmark 2." (
