any advice for working up a load for my 280 using barnes 140 grain ttsx bullets and imr 4831 powder

I put IMR 4831 and RL-19 in 25 rounds, each. Topped with 140NBT, and using the middle load from Nosler 6, 19 was superior to 4831 at the chronograph and posted an extreme spread of 20fps.

IMR-4831 and RL-19 as suggested are VERY close to being in the same ball park burn rate wise. Mine however simply pukes out everything but RL-19 for what ever reason.

Don't get me wrong, it will shoot quite a few other powders, but not to anything resembling accuracy, more of a pattern.

You might find seating depth to play a bigger role with those particular bullets than powder type or brand. I know I have in a few other calibers.
