Welcome! Great site here, lots of wisdom, many prolific contributors with everything from hilarious anecdotes to detailed data charts to jaw-dropping pictures of game, grounds, and gear. The gurus here usually tolerate my "book-learnt" ramblings about math and physics as I fish around for others to join me in my geeky, born-again teenager excitement about muzzleloading. They've all either guided me, corrected me, encouraged me, or just politely ignored me. I've never been trashed or trolled by long-time, well-known, or supporting members. The Admins take care of the obvious instigators, or the "Ignore" function can help you build your own fences quite easily.
You stated that you weren't enjoying centerfire seasons anymore, and I wonder if our experiences are similar with how the public land hunting world has been changing over the past generation or two (or more; I was almost completely out of it from 1983-2002 and then only infrequently until I retired in 2013). Going out in muzzleloading seasons instead of cartridge/shotgun was like trading the freeway (90 mph, bumper to bumper & white knuckles) for the back roads and enjoying more solitude, safety, and satisfaction. After a few dedicated ML seasons, I didn't feel like I needed to sandbag my ground blind nor don body armor on opening day anymore. Gun seasons' opening days had the tiny parcels of public land around me looking like pumpkin patches, and I didn't have the money or connections to access leased private land. Muzzleloading saved deer hunting for me; I was ready to hang it up entirely until a friend gave me a copy of the late Ian McMurchy's "Modern Muzzleloading for Today's Whitetails." Another friend gave me a cheap, neglected-but-salvageable ML rifle shortly after that, and I haven't looked back. I hope your switch becomes as satisfying as mine has been, whether it's a clean break from centerfire or just adding another way to go about it.
