I take my 700 BDL in 35 Whelen on the fly in moose trip. Room is at a premium in the 180, so just the one gun. It wears a VX-3 on QD rings, so if in the off chance I get some scope death, I can still use the irons sights. On the last range trip, I wasn't so bad with them either.
Other trips though, generally see me pack my Cooper in 280AI as number 1, and the Whelen for backup. Now that I have finally found decent rifles for my two sisters that hunt most often, I don't have to bring anything else with me for the family hunting but I do bring my BAR 270 and 94 just in case someone is in a bind.
