Ruger pcc accuracy

I am going to say kinda no... a lot more weight banging around while cycling.

And most pistol bullets aren't designed to handle the extra RPM's from the added speed, I felt like some of the cores might be slipping in the jacket.
I will say all the bonded bullets I tried in my 9MM Colt Pattern PCC performed noticeably better in the accuracy dept, at 100yds.

You might find this chrono data interesting.
