I have built a ton of 6.5 swedes, and the 6.5 x284 is another animal. I have built 7 of them, and am currently building one. I love the old 110 long actions, one I am building is a 30/06 action. In most short actions, you cannot have a repeater , and have the longer 140 and longer bullets set up at the premium length for accuracy, they are too long to function thru the mag. As far as feeding goes,mine have been flawless thru the long actions. I have 96 swedes, 98 actions I rebarreled to 6.5 swede and a long action 110 with a douglas stainless match barrel, and at long range the 6.5x284 does much better, especially with 26-30" barrel. Dont get me wrong, the swede is my alltime favorite cartridge, and have taken a ton of deer, yotes and chucks with them, built over 100 in the last 25 years. JMHO.
