What bullet were you running in the linebaugh? I have a bfr 475 but I don't pack it much because it has a 7.5" barrel and my mountain gun just carries and handles better. I do have hundreds of 400 g gold dots in 475 and I've loaded them up to almost 1400 out of the bfr. I also have a 400 g Lee mold I plan to play with soon too. Maybe I could get the bfr docked to 4" barrel and make a carry gun out of it.
