Trophy Bonded Sledgehammer FMJs, Tough on bore?

[Ray B]

I recently got some Trophy Bonded Sledgehammer FMJs for use in a 470 NE. I notice the color is similar to the Nosler Solid, which I have read is tough on the bore and the fouling is very difficult to remove. The Trophys resemble the Nosler more than other brand jackets, so I'm wondering if anyone has experience with them and if they have presented any problems in their use.

I believe (could be wrong) the noslers fowl so bad due to the lack of driving bands. I am unsure if the sledge hammers have them or not.

The Trophy Bonded Sledgehammers that I have are not banded, however they don't appear to quite as much bronze as the Nosler. Pictured are a Hornady DGX, Trophy Bonded Sledgehammer & Nosler Solid. Base diameters are .4738"; .4738"; .4733". Not sure if the Trophy bullet shown in the previous posting is mono-metal. the one I have is lead core. In looking at the picture I got the order wrong: they are Hornady, Nosler & Trophy. The Nosler is .4733". the other two are .4738".
