Well, I guess I am the cheap skate n this question. I always use a cartridge holder on the rifle stock usually a Uncle Mikes which holds 10 rounds but I place one full backup load in this holder. If it is on my DG pachyderm rifle I place one extra soft in the last loop at the butt and 4 solids in the loops towards the trigger. I also use a Uncle Mikes 10 round holder that slides on a belt along with my knife and leather man. The same with the PG and cat setup except all softs on a separate belt.
