All,
I'm wanting to go from a 124 grain RMR plated bullet to their 147 grain hard cast bullets (Brinel hardness of 18), and am looking for a load using Titegroup, HP38 (231), or WST, as these are the only powders I have on hand.
I also have 700-X on hand, but from what I've read, it doesn't meter well through the Lee autodisks.
Reason for going to the lead 147 grain bullet is or less recoil when I shoot IPSC, and it's more economical than plated 147 grain.
In the past, loading for other manufacturers of hard cast bullets in 9mm has produced leading, no matter how light I go.
Other bullets were 16 Brinell rating, by the way.
I load a ton of hard cast 45 acp using these powders with no leading at all, and some of my powder loads I use in 45 are pretty close to what I'm using in 9mm.
These will be fired from a M&P Pro and M&P Core with 5" barrell.
Thanks!
