Not just from the last ownership fiasco, though they had some. What comes to mind; .244Rem. Introduced at some time a .243Win. Problem: barrel rate of twist. Rem was built to shoot 80 gr bullets and was VERY ACCURATE. Accuracy was good with 90 gr. 100 gr bullets would not stabilize. .243 was developed for 100 gr bullet. Rem had better round, Win had better sales. Rate of twist changed, name change to 6mmRem; too late. 5mmRem rimfire Magnum. Lack of firearms chambered for it. Amazing cartridge. Didn't catch on. Much better round than the .17MRF. .30 AR, too much cheap 7.62x39, no marketing. .260Rem, amazing round. Mimics 6.5x55 ballistics (popular for over 100 years) using easy to get .308 brass. 6.5-.308 wildcat being shot by target shooters for years. Lack of guns chambered for the round. Should have been available in 700, 7600, 7400 and DPMS ARs. 6.5CM comes along, boat loads of marketing and hype, history. 7mm Rem Express, amazing cartridge, killed because REMINGTON didn't market the superiority over .270 Win and O'Connor hype. Remington releases the 7mm Rem Mag AND marketing, instant success. Renames 7mm Rem Express to .280 Rem. Too late .17 Rem, close but not quite. Others are out there, if I think about it. But, this much thinking gives me a headache. You have a favorite, that Remington failed to support?
