What caliber are you shooting? I am new here also don't have a lot of knowledge on Ml"s but see here this group of guys seem to know a lot about the subject,all from bullets to barrels to rifle twist,and powders.My frist muzzle loader was a Wolf.I bought a box of pellets some bullets an learned how to load.The guy who got me into it was pretty good,bought a second wolf with the quick release breach plug which doesn't release without a pair of pliers,the 3rd ml was a triditions 50 cal side lock which i havn't shot yet,this one reminds me of the old guns of yester year.Flintlocks go back a lot further then i really want to go,anyway back to sabot length get different sizes try till you find what works for your ml.Lot of different stuff to play with in this sport.I'm reading a lot of old posts here some interesting some not,the more you know on any subject the better you become with it.
