I have bought some Barnes X bullets in various calibers at estate auctions and yard sales. The darn things shoot pretty good. I had a friend use one of my 300 Savage loads with 130 gr X bullets shoot a cow elk at a little over 150 yds in the chest. In the front and on out the rear..and not very much meat damage.. It was DRT. I have some I'm going to load for the 257 Weatherby I bought. Hope they shoot as well as the Noslers I've got. My plumber friend shot his 'lope the other day with my Weatherby at about 225 yds. He stated it didn't even quiver after the shot. Now he wants to buy it..Nah...Think I'll keep it.. Have worked up a load for the 300 H&H with some heavier X bullets. Let ya know how they do..
