They are typically exceedingly accurate and have a transfer bar which pleases me.
Another big plus for me with BFRs is the free wheeling cylinder.
I have an older BFR in 454 Casull with the same grip as a SBH. That's my favorite grip style. I removed the rubber grips and replaced them with SBH grip panels from Badger Custom.
I'm guessing you guys are talking about the newer grip style on BFRs. I have one in 44 mag but have only fired it with the factory rubber grips. I've been happy with those grips on it. From the way it sounds, I should probably stick with that grip.
