I’m not so sure about that. The industry does what it always has, and no- it was not generally understood what modern case and chamber designs did, nor what optimized bullets could do. In 1925 Winchester didn’t go- “you know, the 6.8 western is better at MV ES and SD, accuracy, precision; high BC (what’s that?) bullets extend range and reduce wind drift, and minimum spec chambers increase consistency from rifle to rifle- but we’re after “reliability”””.
No, they made cartridges the way that they always had. The amount of people that understood anything about what we see as modern case designs could have fit at a family dining table in the 1950/60’s.
More disinformation!
There was a very active and innovative shooting community in the 1950-1960 time frame. Have you ever
heard of the 7MM Mashburn/ 7MM Super Mashburn, designed in the 1950’s doing what the modern 7MM STW can do today except they were doing it in the mid 1950’s. Obviously you are not familiar with Warren Page, Bob Hagel, Vernon Speer. I had hunting/shooting/ firearms mentors in the 1970’s-early 80’s that made me aware of what you are saying never happened in the 1950’s . These guys were using 7MM STW type rounds in the 1950’s and actually hunted A LOT!! They also used Vernon Speer’s (Speer Bullets) ballistics lab in Idaho. In those days, shooting publications were quite popular. Wildcat cartridges were always in the forefront of the shooting articles. In those days you didn’t need to wait 10 years to draw a tag. Many hunters hunted mule deer and elk in five or six states, mentors of mine went on 21 day mixed bag hunts killing moose , stone sheep, caribou and the occasional grizzly on the same trip. Guess what? They used 7MM Super Mags , same as todays modern 7MM STW’s .
You need to read some history on cartridge designers , hunters and gun writers of the 1950’s. I suggest Bob Hagel’s “The Game Rifle”. He speaks of never shooting at big game over 600 yards among other ethics on hunting big game.
