Been looking at some cast hollow point bullets for 357 and 44 magnum.
Lots of good stuff at GT Bullets, but their product is 2-2-96 alloy which is around brinell 10, and bullets are not gas checked.
I feel this is way too soft for magnum loads, but good in "slow" loads like 38/44 Special and 45ACP.
Thoughts?

That is probably a great alloy for the older subsonic rounds. I've mixed wheel weights 50-50 with pure lead and didn't lead my 1911 barrel but they are sized and lubed right.

Fit to the barrel is critical and so is the lube. Most factory bullets use a lube that is too hard due to manufacturing and shipping constraints. There are a lot of variables that start coming into play as velocity is increased in cast bullets and increasing the hardness of the alloy is only part of the equation. The lube will need to be changed also and then there are some guns that don't seem to like cast lead bullets.
