Reloading for .408 Cheytac

[Silas]

Hi, I am UK based and have just acquired a 408 Cheytac, I have cases and make my own projectiles, what I cant find is any loading data, apart from 125 grains of Retumbo, which we dont seem to have in the UK.
Can anyone share data using other powders. I have 2 bullet weights currently a 420 and a 440 grain,

Thanks

Do you get ADI powders there? if so Retumbo is the same as AR2225, also VV N170 should be a good powder any slow powder on a burn rate chart close to Retumbo will work just make sure you start with a powder that is close in burn rate then back it down only 5% and work up carefully, i would also contact VV as they might be able to give you data.

Thanks Wild Bill, no we dont get AR powders here, but I checked out their website and they have a usefull powder equivalant chart and they show RL25 and Vit 24N41 as being similar. Both of these are available in the UK.
