Quality Hardware 44 M1 carbine

[rmcc]

Picked this up a couple of weeks ago and took down to range to testfire. Using LC 52 ammo, after a couple of sighters and adjustments, it would ring the 8" plate everytime if I did my part. Was shooting offhand just for function. Came home and threw the empties in a can and just got around to resizing them this morning. I had a hand full of WCC empties mixed in with the LC 52 that were fired at the same time out of a different mag. Went to size them using Herters steel size die, Midway spray lube, RCBS #17 shell holder, on RCBS 50BMG press. The WCC sized easily and slides right out of shell holder. The LC 52 started to get resistance about 1/16 to 1/8 off shell holder. If I forced to resize all the way, the brass flowed into the shell holder and had to be driven out.
Got the rifle out and tried some of the LC 52 that had not been totally resized. They dropped right in and cycled fine. If I had an oversized chamber, wouldn't the WCC be bulged too? My battery is dead in my micrometer so I could not measure the heads. Just wanted to get you guys' opinions.

thanks,

It could be your lube. I never liked any kind of spray lube.
The LC 52 brass could be thicker too.

Imperial Wax, Royal Lube, and that type work better on cases shot in big chamber milsurp gas guns. Even STP if that's what you have.
The LC cases may be harder and not spring-back any after being fired.

Check that LC 52! It sounds like you may have some of the Chinese Berdan primed stuff. Look inside and see if it has one flash hole or two. If two, junk it and scrub your carbine several times and pull the gas piston and clean the cylinder too! That stuff is corrosive. The resistance you feel is likely the primer pin tip trying to push through the center of the base between the two flash holes! It usually comes in a plain box marked 7,62 mm.

Not Berdan is in LC repack bandolier. Starting to think bad brass. Other rounds fired sized normally. Thanks for the replies!

There once was a 44 mag built on a carbine action, but it pump action. When I saw 44 in title that is what i thought it to be.



Introduction

The Universal Firearms Model Vulcan 440 pump action carbine in .44 Magnum appears in the Universal Firearms brochures from 1963-1967. While the rear half remained similar to the M1 Carbine, the front half was redesigned to accommodate the larger .44 Magnum cartridge by eliminating the short stroke gas piston and converting the action from semi-automatic to pump. The carbine also uses a larger barrel.

The total number produced is estimated at 1500.

The Vulcan was born out of an interest in a carbine using a cartridge more powerful than the .30 caliber carbine cartridge, which was the subject of much experimentation in the 1960's. The Vulcan was never intended as a replacement to the M1 Carbine. It was primarily designed for hunting, at ranges suitable for the carbine barrel length using the .44 Magnum cartridge.

The M1 Carbine has survived for various reasons, the most common being they are just plain fun to shoot. The Vulcan takes the fun to a higher level, in spite of being a pump action instead of semi-automatic. All of the owners I've spoken too so far really enjoy their Vulcans. I evaluate a lot of carbines and cannot afford to keep them all. Every once in awhile one comes along that's a keeper, and my Vulcan is one of them. My son having joined me the first time I used it, shares the same opinion. This carbine stays in the family. It's not a sniper rifle, but you don't want to be the target.

There was some stamped LC 52 brass, possibly Chinese that was berdan primed.

I have a pile of LC 55 brass. It was slightly more difficult to resize compared to commercial brass, but not anywhere near what OP describes.
I just chalk it up to being age hardened after 69 years.
I lost 50-60 of them on the first de-priming. Those had primers that were fused (corroded, not crimped) into the primer pockets. Several reloadings later all is well now.
It does appear to be a little thicker brass.
