3 or 4 in the mag. Or a loaded ML with 2 or 3 backup loads. Or 2 or 3 arrows.

For bp I have one in the gun and three speed loaders in my pockets.
For my 7mm I have four in the gun and three in my pockets.
For my 12ga. I have three in the gun and five on my side on my belt.

Muzzleloading: three extra. Cartridge rifle: usually magazine capacity, except single shots: then usually a leather shell holder of 5.

Who do you get your 3-1/2" slugs from? Thought about carring them for bear recovery.
Here in Il, I carry a ML for deer season and carry one in the pipe, 2 in SL's in my pocket. That and I carry a single shot .44 Mag as well. One in the pipe, 3 in pocket as well. I started carrying a .460 last year, but it is REALLY rough shooting it from a pop-up blind. Muzzle blast is a BIATCH!!!!

3 arrows in the quiver, and 3 speedloads for the ML. I don't rifle hunt nomore. I did when I 1st started hunting and I carried so much ammo it was embarrasing. The deer could here me coming a mile away with all the clinging from the shells in my pocket.

It varies depending on what gun I'm carrying, but usually enough to reload twice. Better to have them, just in case.

This season will be my first ever gun hunt I used my bow all last season and enjoyed the challenge. I bought my ML this winter and can't wait to use it this weekend hopefully. Thanks for asking the question because after reading the answers I got an idea about how much to take. I was going to say 2 loads for my ML,one for the deer and one for me for missing but if I missed the deer I may miss myself so I better take 3. All joking aside I got my ML zeroed in yesterday and if I miss it won't be the ML fault that thing is spot on at 100+ easy.Good Hunting to everyone,by the way I will take at least 6 loaders with me,yotes and a big cat are in my area. Someone released a panther in our area and it is very active even the game warden has seen him and has told us to put a round in him if we see it. A nice mount he would make. Later

4 or 5 in the gun (depends on which one I take) and I cut the plastic bullet holders that come with the Federal ammo I use into a couple of pieces that hold 5 shots each. The holders keep the shells from clacking in my pocket and are easy to use if I need to re-load. I keep one in my pocket for a quick re-load and the other one on my pack just for the security of knowing I have more. I can't think of anything worse than having an empty gun in the field and all the bullets are back at camp or in the truck. With the ML I have the gun loaded and carry 3 speed loaders.

My philosophy...better to have it and not need it than to need it and not have it. Good advice for many aspects of life. That said I carry 1 box (-4 in rifle).

I have my gun loaded 1 in the pipe and 3 in the clip then i also have 7 extras in my coat pocket.
