Parker Hale went with what is essentially a magazine for the M-14.
The question is:
Did they reduce the spring "force".
I ask because I have been involved in using M-14 Mags in bolt-actions and the "full-strength" spring causes all sorts of dramas in feeding.
The main issues with "full-strength" springs are:
1. A ridiculous amount of "drag" on the bolt from a full stack of cartridges.
2. A nasty tendency to "spit out" cartridges during slow feeding.
Shortening the standard spring "works", but a better solution would be to wind a "lighter" spring to the same form but using thinner wire.
Stock M-14 mags are designed to work with the incredibly fast action of that rifle's bolt, and in "adverse" conditions.
Think about the seeming "lightness" of a standard Lee Enfield or Mauser magazine spring compared with the M-14 Mag.
How "heavy" is the mag spring on the Accuracy International?
