Need a harder alloy?

That is much more like what they should be dropping those at. I cast at 710 -725 degrees. I also use a Lyman dipper with the spout hole drilled out larger to get the 400+ gr of alloy into the cavity as quick as possible. Suggest you might try those bullets "as cast"

I'll definitely be giving them a try, I've always cast from my Lee 10lb pot directly. I've never tried ladle casting mainly because what I'm doing has always worked for me.

I shot a few rounds with the 405gr .461”- .462” bullets today. Performance seemed about the same as with the .459” bullets. But the .462” bullets save me the extra step of sizing so I’ll just stick with them.

Besides all that your neck tension is too much, for a flop top you can seat them with your thumb

My RCBS expander die is adjustable to where I can seat the .462" bullets with my thumb.

After some more testing I seem to be getting the exact same results with the 405 gr hollow base bullet sized at .459” over 60 grs of Goex FFG as I get with the same bullet sized at .462”. Both cast from 16:1. So I’m guessing that 16:1 is soft enough to obdurate. I have yet to do any shooting with the 500 gr semi pointed round nose sized at .462”. That’s next on the list.
