How many days? What time of year (temp/weather)? Are you going solo or can you split the load with a partner? Are you interested in using a dry bag on the load shelf? Are you taking a spotter & tripod? What size bag are you currently fitting your stuff into?
Iv done 2 days 1 night with the 22mag a few times,,, could prolly squeeze 3 days 2 nights,, but it’s pushing it if you make a kill. This year I planned on camping and killed first day. Ended up carrying my tent/bag/pad out in a trash bag. (With a 44 mag at home woops) I coulda pushed the bag off the frame and used the meat shelf but hadn’t experimented with that prior and it was getting dark..
