Tradex also carries Sellier and Bellot. I have used a lot of the ammo in 7x57 and 7x57R. If is excellent brass, the bullets kill well and in the guns I shot it out of it was hard to make hand loads that were more accurate. At $28 a box, hand loading also isn't all that much cheaper. Buy 20 boxes at once and the shipping is free.
