I'm going to have some .243 win loads put together , and the powders i've narrowed it down to is RL17 and IMR4350. I'll be using the sierra 85 gr hpbt, fed cases, not sure which primers yet. I'm leaning towards the RL17, but have only found a few loads for it online. Anyone here have a RL17 .243 load worked up for the 85 gr sierra hpbt?
