Swift Scirocco Bullets

I recently returned from a deer hunting trip and was fortunate to harvest a nice muley, I was using a .300 Ultra, handloads with the Scirocco bullet, and I would like to report that I recovered the bullet, and it was amazing to me, I reloaded the 180 gr., the shot was 153 yards broadside with a muzzle velocity of around 3440, the recovered bullet weighted 143 gr. and the diameter was 1.382. I have always been a fan of Nosler's Ballistic Tip, on deer size animals, but this bullet is superior, any other similar experiences or tories on this bullet? But do think this bullet would be to fragile for elk?
