Remington 24 was originally made for the .22short standard vel round.
After the 22Short HS came out,,the Model 24 owners manual had a change printed on the first page recommending 'Remington Kleenbore Ammunition'..."Either regular or High Speed types are suitable".
Earlier manual mearly stated '..standard .22 caliber short cartridge..'
Ammunition recommended was 'Smokeless Greased' cartridges (IIRC that was also roll stamped on the bbl)
The Remington brand ammunition recommended here was 'Lesmok'.
Wether the the differences above came about simply because the cartridge itself evolved into a HS loading and the manual reflected that,,
or Remington made a change internally in the rifle (stronger recoil spring), I really don't know.
But I suspect the latter.
That based on what other designs had to do (Colt (Woodsman), Marlin(39),,) in the same era when faced with upgrading guns designed for standard vel 22 ammo to shoot HV 22 ammo.
Plus it's a balanced blow back system. You can't really compare it's strength to the Win '06 or the Rem 12. Both of these are manual repeaters with solid bolt to receiver lock-up.
The M24 simply relies on the recoil spring and weight of the breech block to balance the force of the round being fired. A blow-back system.
Weaken the spring or increase the force of the cartridge being fired (Standard Vel the HS) against the breech block and something gets damaged.
