Most, if not all, could easily go back to lead in their 12ga. The little guns will take the TSS hit. It will doom the .410 and 28. Last Sunday I did my annual red dot sight in check shooting one Apex Ninja through the .410. Thankfully it was still on. It was $8.00 well spent. If the price doubles it would be $16.00 well spent. I'm still of the opinion that few new hunters spend the money to properly test TSS loads at various ranges now. They rely strictly on the hyped up reports they are reading about. Going to be interesting.
