garand and a case seperation

[corey4]

a buddy of mine inherited an M1 garand from his grandfather a few months ago.

he was out shooting it today, with the proper surplus ammo, he made it a point to educate me there is a difference a few days ago.

anyways, he had a case separation, said he could definitely tell something was wrong. should he be worried about harming the gun?

Re: garand and a case seperation

What is proper surplus? New 3006 like Remington or Winchester are a no no in the Grand.

Good luck

Re-cycle

Re: garand and a case seperation

MJ1...

Please expand on that. I have read about the differences w. 5.56 and .223 commercial. But not about the .30-06.

I've only shot my Garand with US surplus ammo. Which is running out... so knowing more would be good.

Can commercial cases be hand-loaded to something the M1 is happy with?

Edumacate me, please!

Cheers,

Sirhr

Re: garand and a case seperation

Not really, it's a case head problem at the web being to thin. Buy military brass if you can find it. I'm shooting 40's, 50's and 1960's brass. Or buy a case or two from CMP I think they still have Korean and Greek PS,PA and HXP loaded ammo and you save your brass.

Good luck.

Re: garand and a case seperation

With the propper powder, specifically, IMR 4064, you can certainly use commercial brass to feed an M1....I have loaded and fired literally thousands of 168 SMKs in Winchester cases.

See, e.g.; Zediker.com Loading for the M14. Applies to M1 too. Do what he says and be happy.

 

[MJ1]

Re: garand and a case seperation

Corey what was the head stamp on the separated case?

Use Winchester and Remington at your own risk then.

Read Zediker if you can take a grand headache and have a ton of money. Most reloading manuals will do fine for the beginner.

Re: garand and a case seperation

Very little from the OP here - but what type of receiver is it?

Head separations on new ammo normally is from grossly excessive headspace. The non-USGI receivers stretch from being soft and are often suspect in your situation. Also, some from-parts guns can be grossly out of headspace as well.

Yes, repeated case separations can damage the rifle. The gasses erode the sides of the chamber.

Re: garand and a case seperation

You need to stay in the 4064 burn rate for powder in order to have the M1 cycle correctly. Some commercial ammo uses too slow powder. This can cause the bolt to break the back of the receiver.Get a loading maual like Hornady. They have M1 Garand load data.

 

[MJ1]

Re: garand and a case seperation

4895 and RL-15 are the correct burn/pressure range with 4064 and RL-19 a close second for 168 and larger bullets in most reference material. I use both depending on the range limits but that is just my .02 on my ranges.

Good luck

Re: garand and a case seperation

RL-22 is WAY TOO SLOW for a Garand. Slow powders is what hurts them. The slowest thing to be run in an M1 is IMR4064.

Re: garand and a case seperation

MJ and 9H

it is not my rifle. i do not know the head stamp on the case. i will ask him. i have only seen the rifle once.

 

[corey4]

Re: garand and a case seperation

i asked him what ammo and if the gun was all original or pieced together from different guns.

from his text:

"the ammo was korean m2 surplus. it's all springfield armory parts. but i think it was refinished. 1943 receiver but unmarked stock."

he and i are worried that it might hurt the gun. i told him that sometimes it is better to just sit back and enjoy looking at it instead of playing with it. kinda like your wifes' hot friend!!!

 

[corey4]

Re: garand and a case seperation

he said the head stamp is ps-81 korean also has ka 71 and 61.

whatever that means, lol

sorry if i misrepresent what he is saying. im the middle man.

Re: garand and a case seperation

imr 4895 was the powder developed for the military for use in the m1 rifle 46.5 grains in a commercial case and a 168 gr bullet is the way to go

 

[95LTZ]

Re: garand and a case seperation

Some folks may try other powders but for day in day out shooting IMR 4895 & IMR 4064 are the two that almost all go back to. With the standard gas plug the majority of today's 30-06 is loaded with powders that have too much port pressure, which hits the op rod too hard. Hornady & Black Hills have excellent 30-06 ammo available for M1 Garands.

Korean M2Ball is known for having brass issues. I have seen a few Garands in pieces from running that ammo through them.
Many guys have used many rds of it with no issues but I wouldnt fire it if it was given to me
Just my opinion, yours may vary

Re: garand and a case seperation

I use any brass I have for my M1 reloads. Lots of mine is in Remington, Federal and Winchester brass. IMR4895, 150 grain bullets, CCI primers. No issues so far.

Same here except I use mid range loads of IMR 4895. I have never had a single head failure in thousands of rounds fired. I can usually get about 10 reloads before I get neck splits thne dump the brass.

Re: garand and a case seperation

there are all kinds of horror stories floating around about the korean stuff. i would never make a M1 a wall hanger, goes against my nature, the hot friend might be an issue too tho. Lord lead me not into temptation as i don't do so good with it. i'm between garands at the moment, but done plenty of loads for them and load for a buddy right now with IMR 4895 and CCI military primers. be wary of softer primers as had a guy at the club have 2 slam fires in the same day.

 

[JeffinTX]

Re: garand and a case seperation

KA ammo not exactly quality ammo. There were several vintages of the KA that was still loaded with corrosive primers so you may want to check that out and clean the bore/gas system out properly. Not really a big deal as the M1 all shot corrosive ammo in WWII, just have to clean up afterwards.

 

[JeffinTX]

Re: garand and a case seperation

Korean PS stamped ammo was better, not corrosive. The KA 75 in particular had problems with case head separation. Probably way undersized lot that year. KA shoud be generally regarded as corrosive and rifle cleaned accordingly after use.

 

[MJ1]

Re: garand and a case seperation

I have 1K of PS brass and several hundred have three and four re-loads without a hint of web stretching. Helps me save my LC DN and FA brass for CMP. Every now and again after picking up my brass at the ranges I get the Remington or Winchester case mixed in and I can see the ring at the head. Just saying.

Re: garand and a case seperation


Could be an abrasive chamber. Have a Garand smith inspect and polish it for you.

Re: garand and a case seperation

If you had a rough pitted chamber and the brass was sticking either the Op Rod would not cycle or the extractor would rip the rim off the case . The Garand is real tough on brass

Who are you addressing? Nothing wrong with my chambers and it wasn't my brass, it just got picked up along with my military brass and was fired by some other M1 or 03 shooters. For the most part it's a personnel choice or comfort zone for each of us. I'm just lucky to have two full five gallon buckets of once fired DCM/CMP cases. Some of the best I have sorted out are 240 LC 54 MATCH cases I use for my 03's. The oldest I have found while sorting are LC 34,38 and 41 but only a few.
