Gas Operating System ??

At a glance, would you say the gas operating system in a Remmy 742 is more or less "robust" than that in a Garand??
What I'm getting at here is whether it can be assumed (God I hate that word) that one (Garand vs Rem 742) will tolerate "hotter" loads than the other?

What say you??

    It isn't so much the chamber pressure (what SAAMI specs out) but the pressure curve. Wiht some loads - like the Hornady Light Magnum - the pressure curve is changed, which is why the Garand and M1a can bend op rods, etc. With the FAL and the adjustable gas system, you can change the size of the gas port and regulate it to whatever ammo you are using.

    With correct ammo the Grand will last longer, the 742 is nicer to carry. I like the system that was in my Belgian BAR in 30-06.

    One Garand Will outlast 10 Rem 742, OR MORE many Many MORE.

    As far as the gas system is concerned, the 742 has a more balanced system with double action bars while the Garand has a single lopsided operating rod over twice as long. The problems seen in the 742 stem from trying to make a lightweight hunting rifle rather than a heavy soldier proof battle rifle.

    Ya, the Garand was purpose-built as a battle rifle.. tough as a tank and near as heavy after a long march. The Remington autos were purpose built for hunting...easier carry and not designed to be dropped, run over, used like a club, and then keep on firing.

    For an all around never-gonna-quit rifle I'll take the Garand's gas/bolt system.

    One was designed for just a couple of types of rounds and a life span of 100,000 rounds. The other was designed for hunting, with a very wide range of loads and a total life of "maybe" 20,000 rounds

    I will tell you right now, not only will the 742 not tolerate hotter loads than the Garand, the accuracy goes to crap as well.

    I suggest shooting standard loads in your 742. Just like the Garand use faster powders in relativity to bullet weight, i.e. Varget is as slow as you want to go with a 150 gr. bullet. 4350 is as slow as you want to go with a 180 gr. I haven't generally found the 740/742/7400 to be all that accurate either with heavier loads. They work for closer shooting, but I wouldn't range out with them.

    Thanks Sandwarrior, that response was like you had read my mind [;)]
