5.7mm = .224(in inches).... So a 30 cal. wont work because a .30 cal is .076 in. larger than what you need.
You CANNOT fire the .30 Carbine round in that gun. You need to obtain 5.7mm Johnson (Spitfire) ammunition. If you subtract 5.7mm from 30mm, you find that the 30 mm is a big honker, about 1.2 INCHES in diameter, 24 mm larger than the 5.7. The US Military uses 20 mm CANNONS. I'm tempted to say, if you can stuff it in there, go for it. But I fear that you might. I will say, NEVER use ammo in a gun that was not specifically designed for it. Somehow, though, the image of a 1 inch cannon shell being stuffed into a roughly 24 caliber weapon does give me a chuckle, though. Think it through, then try it. A bit of thought here would work wonders. Be careful. No, you absolutely can not fire .30 carbine in an M-1 Carbine chambered for 5.7 MMJ (.22 Spitfire, .22 Johnson, whatever). First of all, the bolt won't close on the round if you try, which is a Very Good Thing. If it did, and you pulled the trigger on it, you would be in for a lengthy hospital visit and short one M-1 Carbine.
If your carbine is a .30 cal, standard carbine mags should work. You can also contact Iver Johnson Arms through their website, or by phone at 321-636-3377 .
Idiot. We have absolutely no clue who "you" is.
I have a Iver Johnson US Carbine Cal. 22LR, serial number 009778. How much do you think its worth
$990
Not much, thinking it was made after WWII.
how much is a Iver Johnson 22 caliber M1carbine.your carbine will bring between 175-275 dollars for a rifle showing between 60%-90% of its original finish,and a good bore.
some sell for 300.00 to 400.00 depending on the condition. here is a website for example-http://www.tacticalinc.com/iver-johnson-carbine-22lr-p-444.html?osCsid=414188ff6da5b9aa8d17a4940b107286
I've been looking all over for an Iver Johnson's M1 Carbine Enforcer. If you would be interested in selling yours, please contact: admin@barbil.com Thanks!
Iver Johnson made the semi auto carbine in .22cal from 1985-1990.They made the Magnum semi auto carbine in .22mag.from 1985-1990.They made the Plainsfield semi auto carbine in .30 carbine,or 9mm Para. from 1978-1993.During this time span they also made a Paratrooper semi auto carbine.I hope this helps.
If it's the Iver Johnson M1 Carbine, they were manufactured from the mid 1960's through the mid 70's. Sorry I can't be more specific.
You need to give the whole serial number.
