I have shoot about 8 boxes of them and have a few more in a draw. They shoot well, not especially hot but very accurate. Based on what I have been able to gather they are designed to be low heavy metal exposure for inside range use. Cabelas also have recently started having "extra clean" ammo at high end prices. I suspect that in some areas that there is pressure to use only this type of ammo. Win-Clean ammo has been around for awhile, never appealed to me but it has a following.
If the EPA continues to be as powerful as it is under the current administration, we may all be forced into using something different.
I purchased most of the TNJ boxes during sales for under $10 per box. I would recommend that you try a few boxes for the experience/education factor.
A friend does reload these with success. Of course, using available components.
