Whatsup guys. So I’ve been going down a worm hole in developing loads for the 410. Being in a lead free state I have to use strictly non toxic. The 410 really doesn’t hold enough steel to have a dense pattern for smaller game like quail and dove which is why I’m tinkering. I picked up some rotometal #8 bismuth because of the 37% pellet increase it has over the #7. Anyone have the data for #8 bismuth around 1300fps compared to a #7 bismuth at 1200? I’ve got some bismuth 410 loads screaming at 1500+ fps but don’t pattern well until I get into the low 1400s. Hoping I can get adequate penetration with the 8s as low as 1300fps.
