I have had a 6mm/.284 since 1964. It is a very accurate and fast round, but the heaviest READILY AVAILABLE hunting bullet for it is the 105 grain Speer, which mine (26" tube) will fire at 3300 FPS. The 6mm/.284 is ballistically identical to the .240 Weatherby Magnum,having the SAME case capacity, and I know no-one who says the .240 Weatherby is equal to the 7mm Ultra Mag., or any other 7mm Magnum!! The 6mm/.284 will certainly kill deer, and even elk, but it is best when used with premium bullets, just like all the 6mm/.243 cartridges. Most of them can be considered deer rounds under ideal conditions, but they are better as varmint cartridges than deer cartridges, and are not too useful for game larger than deer (elk, etc.) IMO, either the .25/.284 or the 6.5mm/.284 would be better for the larger game due to their heavier bullets.

Keep yore powder dry!!
