Buy another manual lol

I have Hornady, Barnes, Berger, Nosler and Sierra Infinity software to play with..... Most of the data doesn't change much unless you're shooting a 'new' bullet.

The one calibre books are good but the info is getting quite old and there are a lot of new stuff that isn't included

All of them only offer an approximation or starting point and will usually require tweaking to suit your own rifle
