The M2 carbine.

[ironglow]

  Almost every GI or Marine's favorite from WW2.. The 30 cal carbine, whether M1 or M2 (M2 full auto capable), they learned to love it!

  The carbine was carried by troops through WW2 and not phased pout by the Army until 1957, when the M14 was issued.

  As a tank crewman in1955-56, I was issued a carbine. TOE weapons for each tanker then was 1) Colt 1911  2) M3 Grease gun and
   4) M1 or M2 carbine..

  I figure that if I were ever smoked out, I would shoulder the carbine, empty the Colt as needed, then carry on with the grease gun..saving the
  carbine for survival usage, once the grease gun was empty.

   Of course, in such a situation, few "choices" are available...
   
  The carbine was most often issued to those on crew served weapons (artillery, tankers, half tracks) along with those who normally did not need a heavier rifle.. officers, medics, forward observers etc.

  THe M1 carbine inspired Bill Ruger to produce the Ruger 10/22, with very similar lines and handling characteristics.  I bopught out one of the first
  few thousand 10/22s sold. ( # 6_ _9 )

my uncle detested them. he was a sergeant and carried one. three of his men were shot and killed by a jap sniper my uncle was shooting at. he said when the jap finally fell out of the tree he had 5 center mass holes in him from his carbine. i owned 3 and loved them. one was my first deer rifle. but then i never faced someone shooting back at me when i carried mine. uncle said many ncos and officers tossed them in the dirt and picked up a garand from someone who no longer needed it

   No question, the Garand was a much superior weapon for confronting a sniper... I used both the Garand and the M14..and they of course, were more capable at longer ranges.

    Of those two, I much preferred the M14..scored expert at 550 meters (600 yards) using iron sights only.  (Probably couldn't do it today  )

  The problem was the mandatory hardball ammo..the same reason my grandson didn't like the Beretta 9mm. He said it was just not a stopper,
   especially when the insurgent has been smoking something.

  When kicking in doors in the urban scene, as in Ar Ramadi, he preferred the Mossy 500 for that need.

In high school, I went to an ROTC camp in Kansas and shot sharpshooter with the M1 and couldn't qualify with the M1 Carbine. Years later, I bought an M1 Carbine and never could get it to shoot well. I certainly wouldn't get another one even though they are neat to "play" with and they look neat, but...

  The carbines I used in the Army, were leftovers from WW2.  They were  inclined to be a bit more jam prone than the M1.

  i don't now if the cause was design, wear or the sand of Fort Dix..

I have looked and looked but -- twenty some years ago there was an article in a magazine (print obviously) about a gent who would convert them to a .375 cartridge.
It was an excellent deer and medium sized game rifle.

I have searched the net but the article died with the print magazine apparently.

  Seems like anything the size of .375 might thin the barrel or bolt rim a bit much for safety.  Still, the new bullets offered and at 2000 fps,
 it should make a good coyote rifle out to 150 yards.

 Perhaps even a decent deer rifle, with good shot placement.

You may be corrct, it probably was to , .351, or some thing similar , been to long time since I read it.
Probably .351 WSL.
