How much H335 behind 123 gr SST?

[603 Country]

I’m pretty much set up to reload a bunch of 123 gr SSTs. Using H335, because I have plenty of it. Starline brass. CCI450 primers. 20” Ballistic Advantage barrel. It all sounds pretty straightforward, but Hornady and Hodgdon have much different views on min and max loads. I’m sure this question has come up before, but I don’t know the answer. Hornady shows a range of 24.1 to 26.4 grains. Hodgdon shows 26.0 to 28.7 grains. Why the big difference? Surely a few of you guys have used H335, so what’s the real world safe range?

I load for several calibers and have for decades, but never bumped into a discrepancy like this. Help me to not blow myself up.
