    I finally scored some 180 ELDs and some RL26. Anybody used this combo in the 7 rsaum? Rig is a shoulder season fun gun with 25" 1-8" HV tube.

    I have no experience with this caliber, but I did model it on quickload.
    the advantage of RL26 is a 139fps faster load than other suitable powders yet the disadvantage based on the barrel life calculator is premature barrel wear.

    here is a scenario but do not use this for load data (max pressures):

    RL26 61.1gn, 64781 psi, 2936 fps, barrel life 1158 shots

    VV N165 59.2gn, 64690psi, 2797 fps, barrel life 2133 shots

    H4350 54.3gn, 64945 psi, 2788 fps, barrel life 1772 shots

    H100v 53.6gn, 64788 psi 2761 fps, barrel life 2440 shots

    What about RL 23 for temp stability?
