A couple things here fellas .
 One of the plus IMO to muzzleloading rifles is there isn’t a lot to go wrong or break .
 That being said things do break .  Sear springs  let go . Main springs let go , flys  snap , so on and so forth . Things happen .
 When it comes to lock bolts , I find most times folks just way over tighten them . When this happens , the softer material of the bolt lets go  thus stripping .
Sometimes all it takes is a bad thread  and you get a striped bolt . It happens to the best of us.
 Frankly  I think your problem is with the quality of the lock  work  not the gun .
 Remember these are assembled pieces  made in different locations by Jukar or is subsidiaries .
Nothing really wrong with that . Most folks find them in most cases  adequate .
 When however they do have problems , its most commonly in the locks . This has held true since the 1970’s both with  CVA , JUKAR  and now Traditions.
 Frankly  is just a sign of the  quality that being paid for  . On one hand you may get a weapon that works flawlessly for years . But you can just as well find yourself with one that doesn’t .
 I think you have done the right thing by contacting them . I have found through the years that sometimes they  are very helpful , yet other times , I get no replies on their warrantee. Most times they are pretty good to work with . Just stay cool  and be polite . Save the tone  for when it starts to look like  your getting the run around .So keep tying .  If they ask  you to send the rifle back , do so . I know it’s a bummer to have to do that  as sometimes it takes a while for it to be returned .
 Sometimes you get your same rifle back that they have fixed . Other times , it’s a new rifle  hopefully without the problems of the old one 
 If however you find your getting no where . Then  simply order  set of new  lock bolts from somewhere like ToW . They’re  of better quality anyway  and you would be far ahead in the long run .
 If you continue to have problems with the lock , then consider replacing it with one like the L&R, LPR’s . these aren’t bad locks and  in fact are a great improvement over the factory lock . Now they will take alittle fitting work but  again you will be far ahead in the long run . .
