Looks like I tripped over a few notions here. The moment I saw that the original poster was interested in a bandolier for shotgun ammo... I didn't for one moment assume that he intended it for sporting purposes.
Well, I answered the way I did because I tried bandoleers for duck hunting under my waders, again to keep 'em dry, and didn't like it vs a fanny pack. I always carry 2 boxes, never shoot more'n 15 rounds even if I ain't shootin' good for a 6 bird limit, but heck, never know, I might not be able to hit squat, has happened on a given day. I don't wanna run out. LOL. Then there's goose hunting, 24 bird limit IIRC (didn't hunt 'em this season), 20 white and 4 dark geese and I shoot a 10 gauge on geese, so I need enough of a fanny pack to hold a couple boxes of 3.5" 10 gauge steel Ts, but I've never fired more'n 21 rounds in a morning, so still,
rather have too much than not enough. That's kinda like combat, right?
Hey, I know some folks think fanny packs are for sissies, but this one's real tree camo. 6 bucks at walmart.
On the skeet range, the shell bag belts are all one needs, or a vest, whatever, shells ain't back in the truck 3/4 mile walk in waders through mud and water.
