5.5" 45 Colt Redhawk
I found the 335g about all I could take.
I had great results with one of the 350--360g choices, but I just could not take the thrust. Same as I went to the 395g and 405g; way too much.
There were also other issues.
The 350-360g bullet that worked so well might have been better served at an ever-so-lessened launch speed, but I was afraid it would lose down-range accuracy.
That's why I tested those super-heavies; I wanted big-bear penetration capability yet something still controllable for further shots.
This remains the reason I recommend the maximum usable 45 Colt weight of 335g: sufficient-to-superior accuracy; sufficient sectional density / momentum / velocity balance; field proven.
