Been a Roberts fan since the early '70's. My current favorite is a BACO FWT launching 120gr Speer Deep Curls at about 2950fps. #2 is an XTR FWT, 100gr Hornadys.
If I were starting today, I'd probably go with a 6.5CM which, as has been said, has identical ballistics with bullets of 120gr and less. But I have too much material and emotion invested in the Bob to change now.
