Nosler dosen't make a partition for the .41 and the Barnes bullet for the .41 is too light for elk. I use the Hornady 300gr .411 flat nose bullet made for the .405. The only drawback is, this won't work in a S$W. The chamber is too short and you have to seat the bullet in too far and it takes up too much powder capacity. Out of my 14" contender I get 1500fps with the 300gr bullet. You should get complete penetration on elk with this set up. Go getim.
