Hello:
I my self had just got a Traditions Yukon .50 & I'll tell ya, it's a good shooter for the money...

My suggestion is to clean her at least after every third shot to keep the breach block from sticking too bad.
You don't have to dissassemble it just pull the breach block out, run a wet patch down the muzzle using the cleaning jag supplied with the rifle followed by a cupple of dry ones & then wipe the breach block off with a wet then a dry patch & the area where the block contacts the barrel will be plenty to keep going during your range time.
