They are usually seeker rounds, making use of a gentler acceleration than a kinetic firing mechanism (which is on the order of 100,000 G). Remember, if the weapon knows what accelerations will occur and can compensate for them, then the suspension will hold.
My thinking is this: the containment unit is at least an order of magnitude bigger than the antimatter. Let's make that two. A bullet weighs a few grams, and presumably can have a payload of say a gram. That would be mostly containment, with about 0.01 gram of antimatter. That has an energy of about 219 tons of TNT - that beats the Russian FOAB quite handily, but is still far from a tactical nuclear weapon. But it shouldn't be too hard to scale things up a bit... if you are willing to get an even more unstable weapon.
