[A 7 Round tube does NOT always fit 7 rounds in the M4]

Okay, so maybe I'm doing something wrong here..

I just installed the 7 round OEM tube and installed a CarrierComp Wolf spring and a CC follower. Even within the spring cap about half an inch out of the tube I STILL CAN'T get seven rounds of Federal LE 9 pellet Buckshot in there. 

I'm going to take the spring and follower out to make sure it's properly seated, but I was wondering if any of you have another suggestion other than changing my choice of ammo. I just bought a case of it, so it will be feeding these shells for a while.

What DFWSFO said.

I'd have to guess there's something different about your follower. Change back to the factory everything beyond the spring and try again. You'd sure think every wolff spring would be the same, but maybe not?

Thanks Deek, I know you posted this a while ago, but I have been equally frustrated with this.  I order the spring from your link and can't wait to try it out.  

Let us know how it goes.

I can't promise there isn't some 2 3/4 shell out there that won't allow for 7 in the tube, but everything I have fits now. I'm just not a fan of trimming springs when there's full springs out there that work.

Solving the problem with an aftermarket spring bothers me

I don’t like it either, but I’ll take a 100% unseen part vs a hit to function any day. 
Unlike you, mine wasn’t even close to fitting 7 unless it was target loads.

This one specifically. It got to be about $35 after shipping.

[M1014 with +2 tube still hold only 6 ?]

I recently got an m4/mag upgrade and dealt with the 6 rounds problem. I could only fit 7 with target loads, 6 with everything else. 

I'm spamming the top googled threads with this reply because got sick of being told it's about shell length and unfixable, or I have to cut my spring to fix it. I could never find a thread that just gave me a clear answer about an easy spring swap or anything else that worked. I'm blown away by how hard it was to find a clear answer on this simple topic.

The fix? I replaced the factory spring with a wolff m4 spring from freedom fighter tactical and it went from being a half inch away from holding 7, to holding 7 of anything 2 3/4" long. It's tight, but mine holds 7 of everything now. This isn't meant to be an ad for wolff, as there may be others out there that would fix the problem, but it worked for me and should for you.

Non-target-load 2 3/4in shells are longer and that's a fact, but assuming your m4 parts are the same dimensions as mine which they should be, your M4 WILL hold 7+2 if you get the spring replaced.

I hope I can bring a few people's blood pressure down if you are dealing with the same problem and as frustrated as me with the threads full of non answers out there.
