I've found it a bit variable pressure-wise, based upon temperature. "A bit" is ridiculously understated. A lot of guys used to swear by it for varmint shooting out of 223's. It should work fine. I think it's mediocre, per your question in your post, for accuracy in every gun I've tried it in from 223 to 444, and the pressure variability spooks me.
My most accurate loads with 40 gr bullets have been with Accurate powders, namely 2230 and 2460, with 2460 being the tops in both a target gun and a sporter. But if you have it and it shoots well for you, for it.
Seafire once posted that he'd had a couple guns let go on him over the years, and every time, 335 was the powder being used.
