I was shooting these EXCLUSIVELY in my rifled 870. Then I got a USH. I expected similar accuracy as the bullet really performs well on game. They tumbled badly. So I couldn't even use them. A friend had a box of Rem Copper Solids and these shot almost one hole @75. This was a number of years back and those orig copper solids are gone, but I gave very good results with BUCKHAMMERS and Ultra-lokt slugs from Remington.
Now in contrary, I bought my brother-in law a USH 20 a couple years later... It wouldn't shoot the Rem slug but LOVED the Barnes.. Go figure.
I hope it works for you as it IS an excellent bullet for whitetails!!
