Thread: 7x57 load

Originally I used N203 in my 7x57, but then had difficulty sourcing it. So I worked up a load using 42 and 43 gns of 2206H. I tried 2206H because my barrel is 18" and needs a faster powder to get some speed. 42gn's of 2206H gives mr 2714fps, and groups of 1.1-1.2moa. 43gns gives me about 50fps faster, but opens up the groups a little, so I've settled on 42. Thats with the 140gn SGK
