480 has got a little bump doesn't it...

I wear a thin leather glove and that fixes that problem (I had the smae thing happening). I just ordered me some 275gr bullets too. The 480 to date only has 3 choices, 275, 325 and 400 grain. I have been shooting the 325's that is the only thing ever stocked around any store I have checked.
I like the gun though. I have a 9" barrel on it and I am looking forward to taking a deer this season with mine.
