Modern ammo in older rifle

1970s IS a modern rifle. Steel has been high quality for way longer than that. Personally I generally wouldn't be concerned about anything built post World War 1.
There ARE situations like this that exist. But you've got to go much farther back than 1970s and a lot of the time factory ammo is ONLY available for the weaker options (eg the only factory 7mm Mauser ammo from Federal is on the weak side to ensure safety in old rifles). If you are dealing with guns made before the end of ww2, maybe do a Google search about it. But unless you're playing with guns that are AT LEAST 80 years old, and likely more like 100+, I wouldn't worry about it.

It is a very subjective statement. What constitutes new or old? Where the instructor was trying to be generally helpful falls short. Yes, there is an age when old steel is going to have molecularly deteriorated to the point of fragility. So, I wouldn't fire modern pressure 45/70 cartridges in a historic buffalo gun or smokeless in something designed for blackpowder. Or maybe modern .303 loads in an 1890s Lee because of design evolutions. But the example of a 1970s Mauser should not be a problem. The .270 is a very well designed cartridge too. Nothing to worry about.
Firearms are the ultimate in durable consumer goods. I have fired First World War bolt actions rechambered for cartridges as powerful as their original rounds. I have more confidence in service rifles than commercial rifles. Perhaps it is irrational, but arsenal built and accepted means more to me than something made to be sold.
Also dont try to run 45-70 bear loads in a Trapdoor Springfield.
Steel and firearms technology is pretty much unchanged since late 1800s/early 1900s.
The main danger is running smokeless in black powder guns. But this is also totally fine in many circumstances.

It's blanket statements like that that perpetuate myths , fear and outright mistruths amongst the firearms community .
Don't take it as gospel, and as far as your 1970's rifle goes, it's hardly old

Look up Intersurplus in the banner up top.
If it was a 972, it was in fact a rebranded PH 1200C that C.I.L. sold under their name.

The 270 Win is a SAAMI cartridge and while the production of the rifle predates the official establishment of SAAMI by one year, 1925 for the rifle 1926 for SAAMI. SAAMI existed before that as a military standard that was during the first world war. The cartridge itself is based on smokeless powder pressures and the chamber is designed for it. Fire away and enjoy with confidence. You may have taken something out of context regarding what the instructor was saying. My guess something to do with the old 303 British. Cheers
Nothing to do with .303’s
Everything to do with Damascus barrels, trap door 45/70’s and rolling block 7x57’s………and stuff like that.

My thought?
Your "instructor" is a moron in my opinion.

It seems the kind of guys that are attracted to being mini representatives of the government get off on making up scary crap to feel important in front of the captive audience.
Very frequent. I have heard this sort of thing many times.
