The L.E. Wilson 45-70 Government case length gage is a precision reloading tool designed to ensure consistent case dimensions in straight-walled cartridges. This one-piece, non-adjustable cylinder gage lets you quickly verify that your 45-70 cases fall within minimum and maximum overall length specifications—a critical check for handloaders working with cartridges that lack a shoulder to headspace against. Properly sized cases improve reliability, consistency, and safety across your reloads.
Built in the USA, this gage uses a straightforward go/no-go design. Simply place your case on a flat surface, slide the gage over the top (with grooves facing up), and run a straightedge across the top of the gage to verify length. The milled surfaces on one end provide the min/max reference points. It's fast, effective, and doesn't require adjustment—you get the same reliable results every time you use it.
If you're loading for 45-70 Government or other straight-walled rifle and pistol cases, this gage belongs in your reloading bench. Note that this tool measures overall case length only; it does not check body diameter or other dimensions. For a complete reloading verification system, pair it with other L.E. Wilson gauges as needed for your cartridge.
