This rifle is a standard remington 700 with the 26" stainless barrel. It shot best with a coal of 3.955 and 99.5 grains of RE-25. That load averaged 3261 fps and .47" group at 100 yards. 98 grains of magpro also gave very good results at 3218 fps. That group was .53"at 100 yards. I used a fed 215 match primer. Both the 338-300 RUM and 338 RUM liked the bullets seated out very near the recommended depth and not seated deep. Both these rifles are so easy to load for they shoot good with most loads. But the .64 bc makes this bullet attractive and it does seem to be an accurate bullet with the limited shooting I have done with it so far.
