Hey fellas, I have finally decided to start reloading for my Remington LSS 7mm Ultra Mag(with a Magna-Brake) due to it getting harder to find ammo for this cannon. I picked up 1 lb of US 869, 1 lb of Retumbo, and some 140gr Nosler Ballistic Tips. For years I've been using the 140gr Core-Lokt or 140gr NP with great success. A friend of mine (who is going to do the reloading) has some Remington brass and CCI MAG primers. My question is: Does anyone have a pet load using either of these powders in their 7mm Ultra Mag?
