Does Quick Load have any info on the 400 H&H ????

Yep 2.846" case, 104 gr of water capacity and 63817 PSI max. Then you simply choose bullet and powder and play all day long.

Thanks, unfortunately I'm running an older MacBook That Quick Load doesn't recognize... hope to get a friend to run it for me

Zephyr--
Be careful with the data.....the quickload notes with mine (in a computer text file) allude to the fact that it has problems with large, straight-walled cases and doing its estimates. I've found this to be the case with the 375 H&H as well, even though that caliber wasn't mentioned. To get my load data and chrono results to be reflected by QL I needed to artificially set the chamber volume up by around 7%. I'm still hoping they will come up with a better fix for that....

Cheers,
