Anybody ever tried double tap hardcast bullets. I was given 50 of the 200gr and 30 of the 230gr. I want to try these to see how they do. Just wondering what powder you used and how they shot? I will be shooting mine out of a Glock 20. any help is appreciated

I have tried their 200gr hard cast loaded ammo out of my 10mm and they performed well out of my Kimber. I load a 200gr cast bullet that I cast and I use Blue dot. They are pretty accurate and get 1250fps from a full charge.
