I guess it's always possible, but all of the Avalanches we've sold have been shiny, but looks can be deceiving depending on the cover stock, color, etc.
I actually like my Avalanche solid at 2000 abralon. It definitely made that ball more versatile and smooth.

I have noticed slight variations on any ball regardless of manufacturer. Maybe when "ball A" was finished the abralon pads were newer than "ball B", so when the polish is applied you'll see some that appear less shiny even though the same process was used.

I forgot who told me, but after the initial batch all of the Avalanches were polished.  I figure it is because the strength of the coverstock is a bit deceiving for a low end bowling ball.
I suggest taking the polish off (somewhere between 1k-2k abralon should do).  
Personally I am not a big fan of polish on Big B stuff.  Only the Red Zone and Fury liked gloss, and everything else has been far more effective at a medium-smooth matte finish.
