Have had a 7 RUM in a Left Hand Stainless Remington with the Grey/Black Laminated stock, for 20 years. Lovely looking rifle that will shoot .3s with 3 shot groups. Thin 26" barrel does heat up in a hurry, but never needed more than one round on any animal. I do not target shoot with it, have lots of other guns for that, this is strictly a reach out there and touch them hunting rifle.
Mine really likes 7828 and Hornady 162 Grain bullets with Fed 215 primers. This is NOT a round you want to load below the max published loads. Do not go below published minimums. They are hard on barrels but they are also an awesome performer. I got 400 brass when I bought the gun and that is more than enough to wear out 3 or 4 barrels. I neck size my brass and am still using the first 50 cases I started with. They have been loaded and fired 6 times each and are sitting loaded on their 7th go around. This usage covers load development of 150 rounds, 2 shots a year to check zero, the rest all used on game.
