Loads needed for #358429 boolit.

[Char-Gar]

Lyman supplies loading data for that bullet and powder that is pressure tested and preferable to antecdotal information on this and other web sites.

There is no difference between Hercules 2400 and Alliant 2400, they are the same powders. Every lot of powders will have some small differences and those differences are taken into consideration by the tech folks at Lyman and other labs in the publication of their loading data. The difference between the "old" and "new" 2400 is no more than a lot to lot variation.

358429 and 2400 powder is a great combination in the 357 mag pistol. It will make you happy.

Old thread, but why start a new one on the same topic...

I use 10.0 grs 2400 and 170 gr Keith 358429. Load is within old Lyman data not currently recommended but I shoot these in Ruger B/H 357 Mag. Very accurate load. I use a heavy crimp (Lee Factory Crimp Die). Lyman 158 gr 358311 gets 11.0 grs in same revolver.
