I have tried lots of bullets, just on paper, just to see if I can shrink my groups. I could never get a partition or accubond to shoot worth a darn in any caliber I have tried. From a 25/05, 270,300 win mag, 3 7mm rem mags and a 338. All of these rifles would shoot a Barnes bullet very good. So thats what I use, the most accurate bullet in a gun. Worked well on the only 2 elk ever taken, and lots of deer
