CMP M1 Garand thread!!!!!

[2761377]

It is common knowledge that bent op rods can result from repeated use of higher pressure commercial loads.

LOL- of course high pressure will damage parts of the operating system, duh.

common sense says to use ammo that replicates original issue.

"Or, better yet, why don't you develop your own equipment/engineering/computer analysis/data to rebut Eric's work. Get an engineering degree if you don't have one already, and some industrial work experience too, so we can consider you a credible source."

better yet, why doesn't Eric produce evidence that specific 30-06 loads have actually been proven to damage Garands. he is the one fooling all you weak- minded followers into buying his product.

until someone proves that any modern, commercial 150 gr FMJ is harmful to the rifle it is all FUD. the definition of which is Fear Uncertainty Doubt. a classic sales techinique

spend your money as you will; but when you tell a noob he needs one of these you are become a encyclopedia entry for Gun Store BS

Didn't bother to read it, did ya?

But why would you? You are obviously a Know-it-All.

Is there any information anywhere that would help me to make a wise choice? Without even knowing what the criteria is, it'll be tough to be wise...

Shipped!

Congrats!!! We look forward to seeing what you get.

I got my serial numbers today and one appears to be May-June 1945. One looks to be late 1954 and the other look like a really late 1955-57. Can't wait to see them Monday. I will post pics when they arrive.

And you guys who have taken this thread OT read the thread title again and get out of the CMP order updates sandbox please. Thanks

[DesertWalker]

My newest (to me) Garand is at the FedEx office. The CMP people could not have been better.......fulfilled the order very quickly, and had to update my file...

I think this SA was built in 1942....

could not be happier...

What is the iron for?

To steam out dents in the stock.

Shooting Commercial Ammunition in your M1 Garand

Even after this well-done analysis came out, there was still plenty of talk on Jouster's and the CMP forum about what the actual impact of the data was.

Yes, it shows that some commercial rounds have higher pressure in the gas cylinder...but there is no data to show at what total impulse the gas piston or op rod starts to get deformation or damage.

Without that data, one can't simply say "because the commercial rounds are higher pressure than M2 ball, then op rod damage will result".

The point is the contrary...

...there are a lot of Commercial Rounds that have similar port pressure curves to that of M2 ball.

As for the question of damage from over-pressure rounds?

You and your rifle are welcome to be the "crash-test dummy" on this one. Higher port pressures result in higher operating forces and bolt cycle speeds, the latter of which is arrested by the bolt's impact w/ the heel of the receiver.

Cracked receiver heels due to excessive bolt speeds, and bent op rods and excessive wear due to system over-pressure, are real problems.

Good lube schedules may mitigate the wear factor, but will do nothing, if not increase, bolt speeds.


I like my rifles, and while they weren't all that expensive, their repair a/o replacement cost would be considerably more.

Not the point at all; not saying it can't or doesn't happen.

I am simply saying that there is no reliable or definitive information about what pressure/impulse will result in deformation or damage. That could be 1% more than M2 ball, it could be 100% more than M2 ball.

Without knowing that, it is not really possible to know what those pressure curves actually mean.

Just received an e-mail from them... will ship in 90-120 days!

[HalfFast]

Nevada you may get lucky! I got that DBU email last week and my order hit the eStore as pending that afternoon. My 3 garands arrived yesterday! I was told the last day they will ship this year is the 19th. 6 days from DBU email to delivery for me, including the weekend they spent sitting in Oakland.

Just a heads up to reloaders; cmp is selling ~250 rounds once fired HXP for $40+shipping.

OK, here is a litmus test...

My father lives in Texas has an order into CMP.

Here is the status so far:
Order Sent: 11/1/2013
Received: 11/5/2013
DBU: 11/21/2013

Update to my dad's TX order. The turn-around times we were getting here in CA are pretty good compared to the rest of the country

eStore: 12/9/2013
CC hit: 12/18/2013
Ship: 12/19/2013
Arrived: 2 SA M1 Garands Inbound

[Nevada Hudson]

Maybe they are processing California's first, before the next new infringement law takes affect.

[Nevada Hudson]

So , did everyone in California get their Garand in time?
Already the first month waiting for mine.
