Hello lkhunte,
First of all congratulations on that fine Bull! Next, trying to be strictly logical here: I have owned a 6.5 Remington magnum since a year before common distribution. you have informed us you have a long action for this rifle, but did not specify the diameter of the boltface, although I am assuming it's a magnum. If you already have a 6.5 x 284, you wil almost certainly be disappointed by the performance you hope to gain from the 6.5 Remington magnum. I have owned both many years. Magnum brass, when you start pushing that case to perform better than your 6.5x 284 will really prove to be a challenge. With the trouble youare going to go through to obtain this brass, you will want to keep it a long time, and you surely won't, giving the pressures you will surely be attaining in order to achieve velocities that exceed the 6.5x 284.
Might I make this suggestion? After decades with the 6.5's I converted a rifle to 6.5 Sherman, a standard bolt faced weapon with ballistics 10 per cent better than my 6.5x 284's; that's 300 fps. Plus you get the advantages of an extra cartridge in the magazine, velocity of a magnum and also using ten to fourteen grains less powder per shot, assuming the right powder. All you would have to do is contact Elkaholic and you would be way "ahead of the game" by only swapping your present bolt and keeping your existing action, a pretty simple thing to do, while reaping some significant advantages.
Take Care, and good luck.
