crofton Posted October 26, 2011 Share Posted October 26, 2011 Why will this baby not allow me to practice with the less expensive wally word value pack stuff .... she just will not cycle reliably. One of the pros on this forum recommended three hundred rounds of bird shot, prior to the the #7's or 8's. Followed his recommendation and now no issue with value pack ammo. 1 Quote Link to comment Share on other sites More sharing options...
Renault Posted October 26, 2011 Share Posted October 26, 2011 Most people will suggest using heavy loads until you break it in. Also what seems to help is keeping your M4 well lubricated... very well lubricated 1 Quote Link to comment Share on other sites More sharing options...
Bello Posted October 26, 2011 Share Posted October 26, 2011 yes run your m4 wet.. and break it in with a few hundred rounds of high power.. mine runs like a dream with crap 2 3/4 ammo Ciao 1 Quote Link to comment Share on other sites More sharing options...
d Posted October 26, 2011 Share Posted October 26, 2011 yes run your m4 wet.. and break it in with a few hundred rounds of high power.. mine runs like a dream with crap 2 3/4 ammo Ciao Yup these guys have the knowledge. I have about 2500K through my short barrel (10") and now it will cycle anything, even with 8.5" of pressure building barrel cut off (all legal and above board with a Form 4 and the blessing of my GOD, my Country, my Mom and the BATFE). But... ... . if you know my mom and she asks, kinda, like, change the subject or something, she wants me to find a wife and a bigger house and well, those things cost money you know?

Unobtanium Posted October 26, 2011 Share Posted October 26, 2011 My M4's run the 1125fps reduced-recoil Remington STS skeet stuff just fine. First rounds I ran through most of them. The trick is to lubricate the weapon properly. Run it wet like an AR with TW25B or LaRue MG lube or Slip2000 EWL or something similar. 1 Quote Link to comment Share on other sites More sharing options...
12508 Posted October 29, 2011 Share Posted October 29, 2011 The bolt likes to be wet as others have said. Mine required about 125 rounds of the cheap wally mart loads before it would cycle them reliably (the federal bulk pack at least). A firm grip/hold also helps with the weak stuff. Last time out, mine only jammed when a small 16 year old boy didn't have it tight into his shoulder. But really, just buy the cheap walmart or imported buckshot and blast away Quote Link to comment Share on other sites More sharing options...
daniel333 Posted October 29, 2011 Share Posted October 29, 2011 you have to remember these guns cycle off recoil... you have to be holding the gun in the right position in your shoulder with a firm hold and you shouldnt have a problem with the light loads. 1 Quote Link to comment Share on other sites More sharing options...
HopetonBrown Posted October 29, 2011 Share Posted October 29, 2011 you have to remember these guns cycle off recoil... The M4 is not recoil operated like the M1/2/3, it is gas operated. 1 Quote Link to comment Share on other sites More sharing options...
Morton Posted April 21, 2021 Share Posted April 21, 2021 It's both, inertial and gas. That's why light loads WILL cycle properly in a brand new M4 if you hold it firmly against your shoulder when firing. Break it in, then you can shoot from the hip.

bambihunter Posted April 21, 2021 Share Posted April 21, 2021 To elaborate on lubrication... Run the bolt wet, but only ever use dry spray for the magazine tube. They will gunk up big time, especially if you are a hunter. I have bought a lot of shotguns from fellow hunters over the years that are "biggest jamming P.O.S ever created". Nearly all were resolved by cleaning out the mag tube. Hunting in the fall, all the foliage is dry. Drop a shell, it picks up grit, or lint in your pocket. It sticks to the oil in the tube. First it feeds too slow to function, and I've seen a few that started using their semi-auto as a single shot after it stops feeding all together. I have to LOL a bit at the guys who have always said the M4's will feed anything and cycle 100% of the time. While it is safe to say my M4's aren't probably past the 500 round mark, so maybe not broke in, I have already had more feed issues with it than I did the last 25 years of my SBE 1. Both are fine gun models though and fully expect it to loosen up. Some of my 1911 10mm's wouldn't feed properly from the factory but a couple hundred rounds down the pipe and they are great; and accurate too. I think the close tolerances that caused it not to feed 100% at first, is also what contributes to the accuracy... Quote Link to comment Share on other sites More sharing options...

This is a common misunderstanding, the either or, black or white answer. It's true that "recoil" and "inertia" are synonymous when describing the action of an autoloading shotgun. Gas is the other type. But there is an element of inertia involved in any gas operated system. This is why my brand new M4 won't reload anything, light or hot, unless I hold it tight to my shoulder. The pistons push the bolt carrier back first, unlocking the bolt, and then assisting the gas pressure still inside the barrel in pushing the bolt back to eject the shell. If I try to hold the gun at my hip, this continuing recoil will push the receiver in the same direction the bolt is going and prevent the pistons from fully assisting the ejection. Once it's broken in, I'm told, the bolt won't require as much assist from the pistons and then they will be powerful enough to do the job alone.
