I use these in my Professional. They had better groups than the lower velocity kind and never any fliers. I never really noticed a difference in recoil.
I use the RBL Professional for deer when I'm mobile, especially if there is a little snow on the ground. I've only ever shot one doe with it but it was a lot of fun to stalk a skidder road in the snow and take it at about 40 yards as it got out of its bed.
FWIW, I also have an RBL 16 and I've never had any problems with the triggers in either gun.
