Just ordered an M4 H2O

[Pudmullet]

Me too, as soon as I get mine and can get to the range, I plan to run it in along with the help of a few other M4 owners who will surely give it a go to see how it compares to their standard M4s.

I have zero concerns about Robar's NP3 coating.

That reminds me, I need to order more 12 ga. ammo.

Not trying to change the subject, but....what ammo should I stock up with? Range break in, target, and home defense. This is my first shot gun other than a couple hand-me-down 20 ga. and I have allot the learn... looking forward to it. I want to be ready when it gets here. Then I'll start looking at lights, slings, etc.......thanks!

While I understand the concept of break in, my personal experience is that mine functioned perfectly with full power buck shot and slugs from the start. So I don't personally see the point of buying cheap trap loads etc to break it in. In regard to target and home defense I still think full power OO buck and slugs is the way to go. It's what this shotgun was built to shoot. As to brands, I'd buy 25 rds of buck and slug from three or four makers and see what patterns best for you and then stock up on that.

I have had the same "load" pattern VERY differently (9 pellet 00 full-power buck) depending on who makes it. Ranging from pure crap, to very awesome. Everyone uses a slightly different buffer, shot hardness, cup/buffer system. See what YOUR GUN likes.

I can tell you from experience with multiple M4S90's, though, that 000 buck through a MOD or looser choke patterns wicket tight. Out to about 50 yards, in a SHTF situation, you can count on at least one pellet making it into the boiler-room on a front-facing adversary. (Note, SHTF does not mean "normal self-defense". It means there's a zombie out there and you need lead on target--NOW!)

I disagree on break-in, though. Not for function, necessarily, but because I refuse to trust a firearm until it has spat a MINIMUM of 500 rounds down-range without a single non-user induced failure. Me personally? I would rather use the cheapest crap I can find for that, and if it stomachs weak crappy birdshot without fail, it's G2G with buckshot most likely. I put a few hundred rounds of slug/buck through it just to make sure, though, but by and large, I feel warm and fuzzy when combat shotguns feed and cycle 2.75 dram target loads reliably.

The break in isn't to test the weapons ability to handle lighter loads, it's to work the internals....the springs. Where did either of you get that he wanted to use cheap shot to break in his weapon? He was asking for types of ammunition for the break in process and for post break-in.

I've bought 150 rounds of Federal's 2 3/4" mag shock 5 shot and another 50 3" magnum rounds. I for one was not aware that magnum came in 2 3/4" so that was nice to find so when I go full capacity on the magazine it's with the powerful round I was looking for.

I have shot an M4 with Fiocchi OO Buck (both light load and regular) so I have stocked up on it and it comes well regarded by two other M4 owners I know. I also have been buying some other OO Buck from other makers to try and I also plan to try some of the more exotic HD rounds along with some regular loads just to see how well it handles them.

Thanks guys!!! Great information!!!

I'm looking forward to playing with it this summer...fall...winter...spring...???

I guess we're all victims of what we read here over time. IF someone asks for info on break in ammo as opposed to ammo to use, it's typically a question about the best fodder to pump through it. Still think sharing that lubing it up very well and just using good buck or slug rounds he'll use later isn't a bad approach for the initial rounds through the gun. While I admit to feeling better about any weapon after shooting a few hundred rounds w/o issue, most of my new acquistions work well from the start and that includes tight custom 1911s.

I'm thinking I might go from light to heavy for the first 500 to 600 rounds. I figure I'm going to have time to come up with a plan and will continue to read a learn from you guys. Thanks for the help!

I also have a 1911, new in the box, never fired. I need to play with that one too....amoung others.

Many types of ammo used in my Benelli M4 Super 90. Have found Federal 2 3/4 low recoil LE 00 buckshot has great pattern and accurate at 30 feet. The nice thing is you can shoot it all day without shoulder fatigue. Makes your day at the range much more enjoyable and still would ruin a bad guy's day for sure !

[Pudmullet]

Has anyone received any updated info on when we may see some more H20's?
