I have crossed paths with Jeremy on this subject on other forums. Any pushback on his claims are met with disrespect.
If a regular here says he personally pulled down the ammo leftovers, calling him a liar seems in poor form.

I fully believe he pulled down 19 rounds of ammo.Quote:

My friend brought his rifle to a gunsmith because it was completely jammed and he isn't particularly mechanical. I wasn't there or involved in any way other than addressing the ammo he handed me and relaying the story I was told.
I don't know you and haven't had any interaction with you before but believe me when I say I truly don't give a damn what you believe. I certainty hope this is our last encounter.
Ok just checking.Quote:

The fact is SAAMI spec commercial ammo is perfectly fine in garands that are in proper working order.
220gr ammo such as rem core lokts generate less pressure than many milsurp loads.
Commercial ammo isn't the problem the Internet makes it out to be.
Good oprod spring and properly greased and you won't have issues with SAAMI spec ammo.
The garand gas system is rather forgiving.
Come on Jeremy! We are not in the habit of calling members liars nor are we going to start now. Let this stand as your only warning.Quote:

The old powder allowed the system to work in time. Modern formulations burn faster, causing the chain of actions to proceed faster than the system is capable of. The system inertia causes the op rod to be caught in the middle between the too-fast gas expulsion as the bullet passes the gas cylinder and a still-locked bolt. BONK!
There is a reason why manufacturers offer "Springfield" load .30-06. It is loaded with the old formula powder and a properly-weighted bullet that leaves the barrel within the capabilities of the gas system and won't cause premature gas expulsion. Use ammo marked "Springfield .30-06" or use mil-surp military ammo for pleasant operation without "parts falling off the man." :madsmile:
Incidentally, this problem, timing due to propellant, was also one of the problems leading to the disastrous introduction of the M-16 in Vietnam as documented by Dick Culver. That problem was too-fast ammunition burn breaking up the timing of the rifle. The rifle was spec'd with ammo that reached a high port pressure after the process of obturation occurred and subsided. Obturation is the process of the cartridge case expanding momentarily from the gas pressure to seal it against the walls of the chamber. If the powder burned too quickly, the gas reached the gas key and forced the bolt open while the case was still obturated. The extractor would simply hop the rim of the case and the case would remain in the chamber, converting the M-16 to a brilliant single shot, manual extraction "mouse rifle," to quote Culver. Along the way of implementing the M-16, the modern, expensive powder spec'd for it was replaced with ball round powder left from the prior wars, and thus the mistiming. Of course, that wasn't the gun's only teething problem but they were all related to budgeting. Culver's explanation is HERE. The mention of this problem is on page 2.

Thats not how it works.Quote:

There is no old/modern "formulations". The "older" powder wasn't slower it was more medium/fast.
the "BONK" as you claim doesn't happen in the garand
As stated above thats not how it works and you can use any weight bullet in the garand with no issues,Quote:
