I never look for .454 ammo, so I duno the avalibility. I myself am not worried. It seems everyone that lives around here that isnt a Lib. has handguns(I do love this town
)! 30/30 is avalible everywhere. I bet the cost of 30/30 ammo is less. But I wold think the extra buck or more would be well worth it!
If ya wana plink, just get readly avalible .45 Colts.
This chambering seems GP to me.
