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.

Thanks...
 
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.
