Forming 50-70 Govt Cases
After the Civil War, the US military standardized on the 50-70 Government cartridge. It only lasted roughly a decade before being replaced by the 45-70 cartridge in 1873. While the 45-70 remains popular even today, the 50-70 is largely forgotten. Despite it's short service life, there are a number of interesting rifles that fire it, namely early Allin conversion Trapdoor rifles and Remington Rolling Blocks. I have a NY State Militia Rolling Block that chambers the 50-70 Government cartridge. Dies and bullet molds exist for this caliber, however brass cases haven't been produced for years and what is available on the secondary market is very expensive, over $5 a piece. I found that 32ga brass shot shells are close dimensionally to 50-70, however they are let down by the thinner rim, which if not addressed can cause excess headspace. Can the rims be reformed?
