Input from another montanan...

I hunt with horses every year...i do two different kinds

Archery- We pack in (usually take two trips 3-4 horses...) and hunt from a base camp that consists of 12x12 wall tent, cots, and bags good enough to -40....cots make a WORLD of difference...We pack with softside Sadlle panniers (they fit over traditional saddle) and we carry traditional saddle panniers that fit behind saddle (like cantly bag, and saddle bags...(personal opinion, Trail Max makes the best system in world!!!) We usually come out once or twice during two week hunt, either to take out meat or to pack in more food...

Gun Hunt- we do a mixed hunt, it is a hunt from our horse trailer and off road (eight miles on dirt road) we sleep in horse trailer (goosneck living quarters) with propane heat etc. VERY cozy...and then we ride horses from camp every day...this is a VERY nice way to hunt....we still set up wall tent and stove etc. etc. but this is luxury (for hunting)
