Here is something I've been wrestling with: if I start reloading 30-30 ammo, should I also have it rechambered to the AI version? It'll still fire standard round, but allow a good boost for reloads.
The AI would certainly give a kick in the pants over the original. Factory ammo will usually lose a wee bit of speed when shot in an AI chamber as the case has to expand to fill the void, but not enough to fuss about, IMO.
