Still riding the back side of the learning curve here. I figured 385⁰F was safe to powder coat but it was just a little too much, my ten test bullets all bulged and slumped the bottom driving band.
So I tried again, switching from 400⁰ powder at 385⁰ for 25 minutes to 350⁰ powder at 340⁰ at 21 minutes. Still a bit much, got a tiny drop of alloy squeezing out on the second driving band but I decided to pop them off with a knife, post-size, and test them anyway, just maybe not at 3K fps! Also finger-lubed and taper-sized some with LBT Blue soft to try conventionally.
Going to start this off at about 2K fps and go up from there.
