You’ve already received some good feedback, and I’m a bit late to the party, but here’s my 2 cents worth! Powder coating lead (cast) bullets has a multitude of benefits……additional available bullet speed without the use exotic alloys and methods is but one.
I use conventional wheel weights for my casting bullets, and once started powder coating …..was immediately impressed!
This is my first group (100 yards) from my Marlin GG, 430 grain powder coated bullets. This was just a randomly chosen load and I didn’t do any more load development. I was satisfied with this, as I have been conserving components for quite a while. It’s likely with more development and a higher power scope, I used a 4x, I could have improved the groups some!
Oh….. I love the 400 grain bullets from my 460 S&W also. But, they’re only running 1500 mv! memtb
