Well,
I would suggest trying the conical bullets that
http://www.prbullet.com/ sells. I think the Keith Nose bullets would be excellent for elk & the QT conicals for anything smaller.
All of the Hornady Great Plains conicals are always a good choice. I' ve had dependable accuracy test results with their 385gr conical in my in-line.
I' m assuming your sidelock is a 1:48" twist - if so, these bullets should shoot every bit as well as the PB (maybe better).
