I have used most of the entire Polywad line at some time or other, and have been very pleased with everything they produce. The low pressure "Vintager" line is great for perhaps fragile old guns, I have used them in at least a dozen different guns with great results and zero problems. In addition, they always have what you need IN STOCK, unlike other possibles sources. I also like their "Doublewide" spreader loads, at the price of some increase in pressure over their Vintagers. They work great when you don't want to open up the chokes on those older guns. I have no connection with the company, just like their stuff.
