Hey fellas.
So im on a reloading bender, I have an excess of surplus 844 and im told use h335 data and i do with good results in .308/.223 but looking to use it in some 303brit 7.62x54r+39.
Now i gots other powder that would work but have so much 844 12lb would like to burn some up ONLY IF SAFE!!!!!
I am comfortable with load work ups so a good starting point would be good.
Thanx

Hi. There's a reloading component retailer who says use H335 data for WC 844. Hodgdon's site shows H335 as one of the tested .303 Brit, 7.62 x 54R and 39 powders.
Can't imagine any U.S. retailer putting something totally 'law suit bait' on their site if it was bad info.
