    Load book calls for WLRM Primers. Doh! I only have the WLR primers. What's the difference, and should I not waste the powder until I get the proper primers? Or is it more dangerous than that?

    Whatever primer I use, will be pushing a 165 or 180 gr. projectile in front of 70 gr. (to start) RL22.

    In reloading for my .300 WM, I use IMR 4350 and started with the standard primers. Things went fine. However, when I tried the magnum promers, my groups tightened up considerably. I presume it is due to better and more consistant ignition of the large amount of slow burning powders. I'd try both if it were me. Good luck.

    critter's right. You need more flash to get that large amount of slow-burning powder to "do righteous".
