Muzzleloader and Muzzle-Blasts will be pretty much your only choices now.
Some folks will tell you that Muzzleloading has a focus on inlines, but they are wrong. Not a bad magazine. Focused on NMLRA stuff but there's take aways for non-members too.
Muzzleloader has lots of good articles running the gamut from guns to equipment, to trekking and history, especially the last few since Jason Gatliff took over and merged it with OTT. It's in color too.
