Barnes reloading data

Could someone look up the data for a 150grain barnes X for a 30-06 with IMR 4350.

I want to try a few before buying the book.

Thanks

I wouldnt go over 59 grains with a regular copper X bullet

if you have a chrony, I'd stop at whatever powder charge averages 2900-2950 fps

Maximum pressure for .30-06 (SAAMI) is 58700psi. with 56.2grain and 150 Barnes X bullet pressure is amounted to 57390psi, which is near maximum, but still safe.
