I'm looking for the advice regarding my muzzleloader should I unload it every weekend during a six week muzzleloading season in which I use the gun only on the weekends it's a Thompson Center bone collector with hundred grains of pellets should I extract the bullet manually.

Or should I leave the pellets in the bullet and simply remove the primer then the next weekend reinstall the primer for hunting. For this weekend I removed the pellets and the bullet but had to throw the pellets away as they absorbed breach lube upon extraction if I do that every weekend for the next six weeks I'll end up wasting and discarding quite a few pellets

Sorry for the typos...
