With my original barrel, MagPro & 130's or 140's gave good velocity but not great accuracy and H4831 worked much better. With the new barrel RL-23 & RL-26 both work good with 145's & 150's with the nod going to RL-26.
Stomatador, what kind of velocity were you able to get with H4831? I have a decent supply of that, and while I hear great things about RL-26, it also seems to have a reputation for pressure spikes at high ambient temperatures, which I would like to avoid. H4831 on the other hand, at least according to Hodgon, is temperature stable.
