You probably know this but during the Army trials prior to WWII the army discovered they didn't like the Pedersen rifle and loved the M1 Garand but they pretty much preferred the 7mm Rederson round. So the original Garand was going to be a 7mm (.276 Pedersen) rifle until they received a "recommendation" letter from the Chief of Staff Douglas MacArthur suggesting the use of the .30-06 cartridge for logistical reasons. That is how the got into the 30 caliber for the Main infantry rifle and the 308 pretty much followed as a shorter, lither and more effective version of the 30-06. We know how good all those calibers are but the thing is, the 7mm projectiles produce more return on investment thanks to the better ballistics of equivalent projectile sizes. They are also "wide" enough to integrate different terminal designs including tracers, AP, AP/IN and lead-free with improved trajectories but w/o sacrificing momentum and terminal effectiveness for any role. They can also translate into lighter rifles, easier to shoot and more accurate (happier shooters). I doubt Remington would do anything to properly market and sell great calibers we have out there. It takes companies with vision and great sales and marketing teams like hornady, lapua, etc... to deliver a good marketing strategy and specially follow through to the end. Remington, like many others, follow the spaghetti approach, toss it to the wall and see if it sticks. They are responsible for abandoning great initiatives before they even got started like the original 6.8SPC that had to be fixed by enthusiasts, hunters and other companies like AR15Performance, Wilson Combat, Federal, etc.. and make it the amazing hunting 6.8SPCII caliber we have today. They also drooped the ball on the 30RAR and made horrible choices with the assortment, case, bolt size, they pretty much ruined the marlin Quality, and the list goes on and on... If I was the CEO of that group I would take those marketing 'Einsteins' and show them the door and then hire young creative and energetic people. I know they have great engineers and loyal dedicated workers so if they just pulled their heads out of their derrieres that would be amazing. In today's world of internet and marketing one can take a turd caliber, wrap it in some tacticool package and sell it like donuts. We have seen that too. At the same time we have amazing calibers and a few wildcats with so much potential but not many know about them and to be honestly the average guy is not going to study ballistics. People want something that is cool, current, fashionable, that works well and is plentiful and with an uninterrupted supply of ammo and rifles for all tastes and budgets. I know markets are competitive and things are hard since Obama Firearms Salesmas of the century retired but what some companies are doing in terms of catalog, quality and service feels almost as if they do not have a clue of what is going on. You see innovation but 90% if powerpointware and the ones that are truly innovators are not enough and too far apart. Thanks God the bullet and powders makers stay ahead and gives us new bullets and powders for all bores and we have amazing dies, presses and rifle actions to work with.
