My suggestions would be (take them with a grain of salt
):
Of the two powders you have, stick with TAC. I've tested dozens of powders in the Grendel and TAC always ends up being one of the better performers. H335 never did work out for me, but every barrel is different.
I have no experience w/ SST's, but have read they are finicky. I use Nosler Ballistic Tips for hunting. They are expensive and hard to find right now, but accurate and always perform well on deer.
Increase your COAL if your chamber will allow it. I've always had good luck starting around .0300" off the lands in the Grendel.
Gordon's Reloading Tool suggests 27.8 grains is your max load at a COAL of 2.256" using TAC. Just an FYI. Always work your loads up slowly and watch for pressure signs.
Again, these are just suggestions. All barrels are different and none of them may work out for you even though they have worked for me in the past.
