I'm not sure which video you refer to (as there are several "comparisons" on Youtube), apart from it not being the one I provided a link to. I have seen such a video and never believe that the camera does not lie :>)

I'm surprised that you haven't made a comment about the shadows on the concrete foreground in this link showing evidence of stop start recording.

The company owner made a video between the M4 and his copy showing the m4 not functioning with the same shots shells that he then puts thru his product with no issues as well as firing a round under water

If he did it in one take shotgun to shotgun that would be believable but the boxes of shot shells amount changes that he shot so take from that what you will

Ah, I have viewed that one. I didn't note what you mention but will try to locate the video and watch again.

However, with the cover extended to NZ's by the Consumer Guarantees Act. let alone a manufacturer's warranty, I am not nervous.

I expect the purveyors "Delta Mike" to be honest and responsible should I have an issue and I bought the beast just to give the fingers to the Show Pony and her odious little Hobgoblin who confiscated my Mossberg Maverick.

Like the Maverick, I may never even make it go bang, but this wee beast not only matches the Maverick, it is an evil black gun with a pistol grip which required an "E" licence last time.......but only an A now..... So I shall make the effort required to go BANG :>)

Heigh Ho, as I get older and the world grows a little colder, my opportunity of protesting let alone finger sticking, is sadly eroded away so I must seize upon any opportunity....however small.

Same reasons as me for obtaining said plaything however I did want it to cycle light loads

I fired up the progressive shot shell reloading press and took some rounds to the range today and have established what pressure range it needs to have to operate in to cycle

It runs better with the tightest choke screwed in and I don't think a lighter recoil Spring will do much as it looks to be on the limit to cycle a round as is so other than opening up the ports abit, my one needs hotter loads

Well done. As I can reload, would you care to share your load findings to save me reinventing the wheel?

Please, please,

My shot at the moment is #4, and Lyman 520 grain slugs but that does not preclude me from increasing the "options" :>)

Made up some 1 1/8 loads with Aussie powders and it was a mixed bag of fuctioning or not, none of the 7/8 loads worked at all but the old favourite of 1 1/8 Winchester 452AA worked a treat so I will make up some more

Have been talking to Delta mike and they say it needs to be run in with stouter loads before it likes lighter stuff for a hundred rounds or so

Seems strange others have been able to run them sooner out the box

I will have another play reloading some other loads and trying them

I have been collecting posts , (some, not all from good members of this site) on this matter of "running in " this Benelli M4 clone

1...Hunting and Shooting comments on the Benelli M4

biggles301 ...........Buckshot is this things favourit

lee308........I had an M4 before the fuckwards changed the law because of their own fuck ups. These benelli only seem to like the heavy shots.
Buck and slug. Light shots are unreliable in these

Rushy.........The spring in these are tight and will not properly cycle 28 gram loads when it is straight out of the box. I use 32 gram loads and have never had a problem with them cycling.

Gundoc......The Benelli and other inertia operated semi-auto shotguns all give unreliable performance with light trap loads. The easiest solution is to just use 32 gram (1-1/8 ounce) loads. They are also very sensitive to body stance, you need to lean into them to get reliable functioning. Leaning back, light body weight, or less than a firm grip will all affect functioning. The large spring behind the bolt head can be replaced with a similar sized one but made from one gauge smaller wire for reliable light load performance but it needs to be changed back for heavier loads.

nowool.........cycling depends on the stock you have: pistol grip stock can handle lighter loads. traditional stock requires 1 and 1 quarter dram field loads. place the stock up against the wall and try firing it.....it cycles you aren't bracing yourself enough. if it doesn't fire then replace the recoil springs with brownells or wolf springs. M3 is great gun but mind you it was designed to function with buckshot and slugs.

How many rounds do you think you have put through total, any jams?

I put through 50 rds of 00 buck no jams. I wouldn't suggest any low brass bird shot until you got at least 200 rds of high brass through it.

Well I figured mine out!! Just thought I would report back here, I was using low recoil rounds when it was brand new, switched to 00 tactical buck shot and she works perfect! After 100rounds of the 00 it runs the low recoil fine now. To bad it's prolly on the fucking list now "

As a result, I now have a slab of 42 gramm #3's to feed the brute until it learns to play nicely.
