I was looking for a load for my Mark 5 270 Weatherby Mag, I have picked out my bullets as I have had Great luck with them for the past 20+ yrs. They are 150gr. Sierra Game Kings B.T. These loads will be used mostly for whitetail & maybe a Mule Deer every now and then. Please if there is anyone out there that know something about this load or loads and don't care to share it would be of Great help. Thank you very much for your help David.
