I only have one 52 and had to look no farther than my first load of 2.6 grains of Bullseye under a 148 DEWC to find a load it likes. A full roll crimp and it just keeps on running. I wish I could shoot it to close to it's potential standing on my two hind legs but unfortunately I have to bench it to come close. Here's a picture of mine since this thread is light on pics.
