"Yes it was put in rifles like the 700, 788 and 7600...but the accuracy was always the issue. Every person I talked to said the anything early from Remington in 244 or 6mm naming didn't do as well as hoped."
Handloaders found that out in spades when they tried loading 100 to 105 grain bullets in the slow 1-12 twist barrels that Remington put on the .244s.
With bullets of 90 grains and below and a minor amount of effort on the handloader's part the .244 would turn in accuracy figures just as good, or better, than anything on the market at the time, including the .243.
"Now why the 788 and 7600 are popular now, you must remember two things. The 788 is notorious for having broken bolt handles, not a problem that a deer hunter wants."
The 788 sold well during its entire production run and was, as I noted, Remington's most accurate out of the box rifle. Yes, bolt handles have been a problem over the years, but the entire 788 subject is, as I noted, more of an aside because it wasn't introduced until 1967.
Remington's pump rifles were always very good sellers, right back to the introduction of Remington's first high-power pump rifles in 1912. Their big appeal was that they provided full-powered hunting cartridges like the .30-06 in an accurate, fast handling, and fast operating gun.
"Browning put out some limited editions in 348"
Sorry, Ty, but to my way of thinking that doesn't come close to a resurection for the cartridge. All it did was give the round a limited puff of life.
The .45-70, the .45 Long Colt? Those rounds have truly been resurected.
