While TC certainly pushes their SW, I don't believe it is made clear to potential buyers that SW may be the only projectile to work acceptably.
If this is indeed the case, it should be made perfectly and unquestionably clear so a potential buyer has all the info needed to decide to purchase.

They should not find this out after spending hundred's of dollars to obtain a gun with limited possibilities for loads.

And it is more than reasonable to expect manufacturing tolerances and quality control to be at a level that the QLA problems they are having should be a NON ISSUE to the customer receiving their new, expensive quality gun. The muchheralded (but not in my personal experience)TC customer service dept SHOULD be something that few ever need to experience IF manufacturing and QC do their jobs.

Working up a load is part of the fun. However, you should not need to be wondering if it is the load or the gun that is the problem. And TC should not expect the buyer to do their QC by spending the time and money for trial loads to determine a gun needs rework or just a limited selection of TC loads(NOT ADVERTISED) to achieve acceptable performance.
