Yeah, 4227 is a little dirty but I’m liking it more and more all the time. It doesn’t have to run wide open like H110 and and seems to provide excellent accuracy in everything I’ve tried it from the 401 Powermag to the 500 Linebaugh. I like it well enough, that I bought an eight pound jug. I’ve had outstanding accuracy with it and 400 grain Bullets in the 480. It’s a winner in the 357 Maximum. Especially with heavy bullets.


Chronographs, bore scopes and pattern boards have broke a lot of hearts.
