Help! I've got an original WW2 Garand!

With the WW2 M7 , the M1 becomes a straight pull bolt action.

Then the theory would fail to make sense!

Anybody actually try launching a dummy grenade lately? My only example was about used up when I got it. Fins bent, nose partially caved in and bent to boot. Pulled it apart years ago to assess the repair possibilities, and have probably lost most of it by now. Have a launching attachment, screw on sight, and a few ballistite rounds, but no "projectile".

Why would it not make sense JM? What would not make sense?

If the bolt doesn't travel to the rear whilst launching a grenade, then the pressure spike is unlikely to exist. I haven't done any studying on the subject in years, and have no first hand experience, so, as first noted several many posts back: it's just what I've read. Could be another one of those myths that just won't die!

As far as the sharp cornered op rods being theoretically more prone to failure, I believe it, but still use them on rifles that have all the "right" parts flying in formation. Too much bother to go swapping stuff out all the time.

A sharp corner is prone to crack, it's an engineering fact...the radius corner will stand up longer. I still think they just go from time and use. Heavy continuous use.

Not a great post, above. Myth of grenade launching causing the failures. In all likelihood the most flogged out Garands were probably assigned grenade launching duty. And one thing leads to another... What was this thread about, again?

Roger, out.

Roger, out.

The "not a great post" was referring to my own. One of those "stay up 24 hours straight" days compounded by pollen attack....

Well gents, now I've read all the warnings - need a relieved op-rod, otherwise... need fully sized cases, otherwise... need reamed out primer pockets, otherwise... need... - I am stuck with a rifle that can't read and so refuses to malfunction. Just functions flawlessly. After all, it's only 70 years old. See the range reports forum.

You don't need help. Except for thinking you'll get it from us. We're here to muddy the waters as much as possible. As far as my range experience goes, the single most important thing for Garand accuracy is good clamping pressure when closing the trigger guard.

Never had the first reliability problem in 25+ years from the first rifle onwards. In fact, the barrel off that first rifle got installed on the CQB rifle and has digested roughly 10,000 rounds (primarily the once cheap berdan primed European fodder purchased by the 1000 round case) , many very quickly doing double taps and "Mozambiques". That barrel has always been terribly rough, but has only needed a crown touch up or three to shoot far better than expectations.

Having said that, parts will now start to commence falling off and otherwise croak...

Exactly...
