What's the biggest round you can shoot well?

[Forrest Halley]

I wonder how many of those that profess their love for the .375H&H use it to hunt elephants on a regular basis?

It is:

"What's the biggest round you can shoot well?". ​

Not what do you go to the range or AH and flex with. Folks are just stating their limitations. There is no shame in that at all.​
