Just my curiosity, but could be a good info for the new to MLing.
I usually carry 6 pre-measured loads and about 8 primers (209s in my case). Never had to use more than one spare in last five years of MLing. The routine goes like that:
- fire the first shoot
- re-load
- look for the deer
- drag it to the truck
- unload rifle and clean it at home
But when I am hunting with centerfire rifle out of state I usually carry about 20 rds. Not that I am anticipating to get in firefight with deer, but it is light and whatever,,, but I carry about 20 rds.
