[True or False: M4 won't cycle standard 2 3/4" loads.]

Without a doubt, if you want BOOM for your buck get the 3" rounds.

I've decided to do 2 3/4" pretty much as my standard, and do wish all the 2 3/4" rounds were the same size.

[I'm sure others know, not all 2 3/4" are the same size!]

I'm fairly new to shotguns, having only done sporting clays until a month ago when I bought my M4.

I've been shooting mostly slugs, and well, the Winchester 1600 FPS 1oz Rifled Slug (X12RS15VP) only fits 4 rounds in the 5 round Benelli magazine tube.

My M4 H20 is 100% stock (no modifications).

NIce slug, shoots well, and never a mis-feed to date, but my Federal 2 3/4 Vitol Shok 1 1/4oz slug rounds fit 5, and my Armscore 12 gauge 00 buck fit 5, and other 2 3/4 have fit.

I just shot the Winchester slugs for the first time today and found out they don't fit 5.

You have an indoor range that allows you to shoot buck?

They don't allow steel. It has to be lead, and I was shooting BB, 4 buck, and slug last weekend.

Makes sense.

I just shot my M4 this past weekend for the first time. I put about 100 rounds through, all lead, 4 buck, BB, & slugs at an indoor range. 2 3/4" and 3". Not a single misfeed.

Thanks for the reply..

Just curious, do people use them in M4's?

These: Aguila Minishell Ammunition 12 Gauge 1-3/4" 7/8 oz Lead Slug 1250 fps

Or any brand?

 

 

[Picked Up an M4 H2O]

I think the cerakote is a nice finish, and as I don't plan on keeping it in a case all its life, the finish will get scuffed over time. Maybe some day I'll redo it to another cerakote color scheme

24 hours though? Benelli does warranty the firearm, if there's a problem with the finish give them a call?

[M4 vs FNH SLP?]

Old thread, but I'm a new Benelli M4 H20 owner. I'm satisfied with my purchase of the M4 for home defense and range.

I'm not law enforcement or military and decided that it is the better option due to FNH SLP's interchangeable gas pistons, among other reasons, for my use. The Benelli M4 is a simpler design in this respect.

I was tempted to get the longer barrel FNH offering for versatility.

 

[M4 Slug Choke Size - Imp Cyl, Cyl, but what if I want to use the modified that came with the firearm?]

Our local outdoor range only allows slugs using their target frames, so I'll break it in using the slugs, and pop off some #4 buck and magnum at the dirt (when the range opens again). I read somewhere they said 50 rounds for break in.

I was surprised to find even 1 box of 00 buck anywhere, let alone Walmart. I'll just save those for the zombie hordes.

[M4 Slug Choke Size - Imp Cyl, Cyl, but what if I want to use the modified that came with the firearm?]

Thanks for the response NoTycoon. I went through a bit of crash course in chokes, ammo, and availability of ammo this past week. I've only shot sporting clays with my 20 gauge over/under using 1 modified and 1 improved modified prior. It's good fun with this nice light shotgun.

Anyway, unable to find personal defense ammo online today, I did manage to find rounds of 2 3/4 1oz rifled slugs, some #4 buck, a box of 00 buck,  and a box of magnum BB locally.

As soon as the outdoor range opens again I plan to break the firearm in. Is there a preferred "break in" round?  I'm thinking quality hi-load target?

[M4 Slug Choke Size - Imp Cyl, Cyl, but what if I want to use the modified that came with the firearm?]

I know the recommended choke size for slugs is cyl, or imp cyl, but:

1. is it OK to shoot rifled lead slugs using the modified that comes with the firearm?

2.. When does modified choke become a problem for slugs? Are there some to avoid?

3. Which Benelli chokes are compatible with the M4 H20? Any of the ones in the Shop section on Benelli Web Site?

Thank you.

[M4 Owners - How did you end up discovering and buying the M4?]

This M4 H20 is my first 12 gauge shotgun, my other is a Franchi 20 gauge over/under imported by Benelli USA (bird gun) which I use for sporting clay fun.

When I started looking into tactical shotguns, semi-auto, it didn't take much time to figure out this was a top quality option. In my opinion the M4 rules the roost in this category, and I believe I'll have confidence it will simply work (after being broken in).  So I found one on Gunbroker, and bought it. I actually bought it twice on Cabelas, but they cancelled my order twice after running out of stock.

Standard stock model (no pistol grip), and It'll arrive later this week.

Now I need a place to shoot it, all the local ranges are closed.
