Pretty much every major manufacturer today advertises that their warranty is voided the moment you fire any reloaded or non-factory ammunition in their guns.
Even most of the after market barrel manufacturer say the same thing... yes BarSto, EFK, Lone Wolf, Storm Lake, Jarvis, etc. all talk about how their rifling allows you to use lead bullets, etc. but they also clearly state that use of reloaded ammuntion will void their barrel warranties.
Most manufacturers will go overboard to stand behind their product if you've followed the proper care and use of their firearms (used factory ammo, etc.). Many will go out of their way to be more than fair even when the user has NOT followed procedures and decided to fire reloads.
In either case it's not unreasonable for the manufacturer to want to examine the gun and evidence and come to their own conclusion... and that usually takes time. If you read through that whole thread it appears that after close examination and review the manufacturer did in fact show that the gun does NOT have a problem firing Out Of Battery and that this was NOT the cause of the failure, contrary to the early suggestions and claims.
Cut through all the BS and claims made in that thread... bottom line is
- The customer decided to ignore the manufacturer's recommendation and use reloaded ammo in his gun (many of us do this too);
- By doing this the customer accepted that he was voiding his warranty on the product;
- The customer had a catestrophic failure of the firearm;
- Regardless of his and everyone else's opinion, there was no clear evidence on what caused the failure until a proper investigation and review was performed;
- The manufacturer responded by offering to review the evidence in order to draw it's own conclusions on the cause;
- This only makes sense as the manufacturer would have a liability issue if they failed to attempt to investigate and prove that the cause was not in anyway the fault of their product or their manufacturing process;
- The manufacturer presented their findings to the customer
- The customer apparently accepted the manufacturer's findings (whether reluctantly or not);
- The manufacturer made a good faith gesture to assist with replacement of the failed product even though the warranty had been voided by customer's own actions... this goes above and beyond what they were required to do;
I've witnessed enough KB's over the years... some have been the fault of factory ammo (even factory ammo will have flaws in their production and they'll stand behind it when it does), some have been the fault of the guns, but the vast majority have been the fault of the reloaded ammo that the user had decided to shoot even though they clearly knew it was voiding their warranty. In many of those cases the gun maker still assisted the user with at least partial replacement or reduced costs.
I think most of the manufacturers do a fantastic job of "making things right" when you have an issue with their product.
Just my opinion
