I use the buttstock carriers on all my rifles but rarely have more than about 3 rounds in them(utilize these carriers as much for protecting the buttstocks on my rifles from scuffs and scrapes as for carrying ammo). Also, buttstock carriers deaden any sounds from brush etc. hitting or rubbing against a fiberglass stock in the field. So, 3-4 in the rifle magazine and another 2-3 on the buttstock sling.
