Guys,

Am using some of the odds and ends I've collected over the years.

Have found a one pound can of WW473AA and a one pounder of WW630. Would like to use these up for practice ammo. 473AA appears to be in the same burn range as #5 and WW 630 in the range of #9.

If I remember correctly 630 was found to be temperature sensitive, but I remember no problems with 473AA.

Anyone have a link to loading data for either powder?

Thanks!

What chamberings do you have as options to make loads for?

Probably going to load medium performance 40 S&W with the 473AA as that is a good burn rate range for it.

Started with 140 gr cast at 6.5 gr and it is a very mild load ... which is actually opportune because a neighbor wants to provide some practice time for his wife. The load cycles a CZ75 and I think will be OK for his XD compact.

The 630 should be a decent powder for 41 and 44 Rem Mag cast bullet loads in the mid range.

I have some older W W load manuels. for these powders but I dont think they cover the 40 cal.
473aa I think was close to green dot for a burn rate.
the 630 was a diffrent breed i used it mostly for 38/357 i kept my loads some where in the middle
