Back somewhere around 2008-2010, after having no luck for a couple of our regular firearms seasons in a row, I suggested to my father maybe we should look into hunting what was then our muzzleloader season.
I didn't exactly expect him to go out the next day and buy two T/C omega inline muzzleloaders for us to use.
I admit to doing it the "easy" way, as I just use two pellets of 777, with a 250gr Hornady SST sabot and 209 primer, scoped with an old Bushnell Scope Chief VI
About the only difference between it and and a single shot centerfire is limited range, longer reloading time, and the cleaning required after I'm done.
This is assuming in-lines are allowed in your location.
I wish our season was prior to the main firearms season. Instead it was first at the beginning of Dec, and then moved to the week from ~Christmas - New Years.
Since they decided to add crossbows as allowed to our archery season, I acquired a crossbow to be able to hunt Sept/Oct.
A 4pt from New Years day 2023, and a doe from Dec 30 this year. The doe was taken Traditions Buckstalker I had gotten for my daughter. As she didn't make it out for the season, so I brought the rifle instead of mine.
Both ran about 25-30yrds and dropped in almost the same spot
