This has all pretty much been covered here: https://bobistheoilguy.com/forums/threads/commercial-ammo-in-garands-test-resutls.385009/ But "modern full pressure" 30-06 has similar pressure to milurp 30-06 so not an issue.

But CMP tests fired all garands ....... Roll eyes

Now that I can see your pic on the big pc. The follower is installed backwards.

Lots of misinformation here. The garand was designed around Ball, M1. 174 GR at 2700+fps MV. Commercial ammo and milsurp ammunition operates at the same pressures. PPU/s&b garand ammo is pretty hot compared to most milsurp ammo. To the OP. Is this doing it with the same clip? Or several...

not a concern at all...if it was they wouldn't have issued it.

Quickload can give you port pressures. powder slower than 4064 doesn't cause any problems in an inspec and properly lubricated garand

Already have... https://bobistheoilguy.com/forums/threads/commercial-ammo-in-garands-test-resutls.385009/ Quickload can get you pretty close by using the muzzle pressure data point.

not incorrect...a light bullet and case full of slow powder has much more port pressure than a heavy bullet. 220gr and a case full (SAAMI max ) of slow powder has less pressure than a 135gr bullet. Kinda moot point as commercial ammo isn't any more dangerous than milsurp ammo.

You could have at least provided the correct weight and pressure... Are you unable to have civil discourse? What part of my post was confusing to you?

Correct...high primers do that.

because thats not always how it works. Our test data confirms this. Powder burn rate is what affects this. Faster powder has higher chamber pressure and lower port pressure...slow powders ..the opposite. What is the right weight and pressure?? Source? It can't change the port...

Oh you can get more...I was there. It's such a compressed load the bullet came back up after seating. I might have a pic of it somewhere

Its not..maybe.. The exact recipe will not be released publicly.

I've seen the heel popped off with a shooter using USGI ammo. Springs springs springs...min length is 19.5" for best safety/reliability. If the pressure of commercial ammo is the same as milsurp then the oprod speed will be the same. My gas trap lives on a diet of M1 ball clone ammo as that...

There is no requirement for #34 primers. Properly seated primers don't cause issues. One exception is Federals ..they are notoriously sensitive.
