After trying unsuccessfully to find reloading data for 325 gr. bullets with Reloader 7 and H4198 for use in the 458 Magnum, I'm coming to the Campfire in hopes of getting the information I'm looking for. Any help with load data for the 325 gr. 458 bullets and powder would be most earnestly appreciated. Thank you.

325 grain bullets in .458 are an oddball size so I have never seen them even though I have used .458's for decades.
You should be able to use 350gn charges as starting loads and maybe get another 2 or 3 grains to suit that weight is you are stuck on it.
Rel 7 should used around 69gn and possibly a couple more grains
H4198 is a good choice but I'd start with 75grains. There is huge variation with the recommended powder charges for this powder and I have see 10 grain variations but because I have loaded a damn lot more than most with this case, I know the charges will permit easy extraction and no signs of excess pressure in this case.
