I bought a box of buffalo bore item# 8a there 430 LBT bullet and noticed that lthey look like small rifle primers. I send them an e-mail and they told me to use small rifle primers when reloading and depending on powder use i could use standard or magnum. Can someone tell me why this brass was made to handle small rifle primers , whats the benifit? I have only reloaded brass made to take the large rifle primers and was wondering weather to reload them or not.
