The Fusions shot under one inch no sweat in my 270. Their performance was the best I have ever seen on deer with the 270. These are big mule deer. They shoot great from my 308 Browning A-Bolt as well. My neighbor used them in his 243 with good results. With the Fusions available, I will never load another shell for my 270. Federal claims the work equally well on Elk but I have not tried them for that. If they shoot good in your gun, you will love there performance on Game.
