I've been working up a load for my 338 RUM which will be used in an upcoming moose hunt. The Nosler 250 Partition bullet was available as "seconds" for a good price so I thought it might be a good place to start. Groups at 200 yds were rather impressive for a non-target bullet so I moved out to the 300 yd line which is as far as you can shoot big bore at my club. Below are the results of two different loads that did well ...... actually much better than I would have hoped for in a Partition bullet at that range. Looks like my search for a good moose hunting load is over.
