243 Winchester: Can IMR 4198 be used for a 100gn projectile?
I'm planning on loading for a buddy with a Remington short action rifle in 243 Winchester. He's looking to load a 100gn J-Word projectile. Unfortunately, the only rifle powder I've managed to scrounge that will still work with my AR is IMR 4198, the eggplant purple stuff.
From my looking through a couple of reloading manuals, it seems that Varget is the recommended powder for the application. I've only seen a single load for a 84gn cast projectile with a starting weight of 16gn of IMR 4198, with a max of 22gn.
Considering that 4198 seems to be a powder that takes up more volume than most, it may likely be unsuitable for this role.
Do you have any loads that would work with this combination of powder and projectile? Or, should I just hunt down some Varget and be done with it?

IMR Load data from 1999 is available.

I'll be sure to cross reference any other media that I can find.
I've also found a load for 4198 in the Hodgon Website!
Starting 32.8gn
Max 35.7gn
These are MAXIMUM loads. I have the same data in an old 1999 IMR manual. IMR lists all powders, some are not a great choice. To slow or to fast burn rate.
With IMR 4198, stay away from maximum. Reduce data 10% work up, stop when accuracy is ok.
I worked up a IMR 4198- 26.0 grs,* load for 6.5 Creedmoor. Very accurate with 140 gr Match Burner bullets.
