    Would you comment on relative controlability, flash/blast, torquing etc?

    Typically the AE, remington 125 sjhp and the 158swc with 2400 are painful with any grips but pachymers. I just got some ahrends and i find the gun is much more controllable. I wouldn't hesitate to carry the remington 125 sjhp which recoils the most, except it shoots low.

    The Golden sabers and xtps recoil similarly.

    That doesn't compute. 6 grains of Unique under a 170-grain LSWC in .38 brass went 1070 fps in my 4" M28 (it's an old .38-44 HD load). I'd re-do this load in better conditions, my guess is that it'd come in about 100 fps faster.
