    I want to load some 180gr accubonds and would like to use some existing RL25 that I have. Does anyone have some load info they could share, using this powder?

    Thanks in advance...gjszabo

    I use 90.0 grains w/180 AB. 3300+ I do have a tight neck BR chamber which drives the pressure up, hence my reduced charge. If you have a factory chamber you may need more than 90 gr. to get 3300 or better. RL25 works REAL well in a 300 RUM.
