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.

I had no problems with mine from day one

Just noticed my comment at the top, that was in relation to a genuine Benelli M3 rather than an M4 clone. Inertia vs Gas so may not be a relevant comparison.

My Tac12 cycles both of these loads with no issues.

The suprema is noticeably hotter than the super 28.
1345 fps verse 1210 fps.
If in doubt, use the suprema.
Both are nice to shoot and are well priced especially when on sale.

What did you do by the bolt release ?

Home made JP type comp on it or is it a bought item

made the bolt release by pushing the original button rod bit out its just stamped in there and welding a bolt in its place then threading a peace of alloy and screwing it on ended up putting a brass nut on to hold it locktite didnt work yes home made jp comp didnt get it quite right will build another but does work

The "Bolt release button" is a bit small and this has appeared as an option.

Perhaps, seeing it is just a piece of twice bent steel, it may end up being an option in NZ.?

I also provide a link to a video https://tinyurl.com/ydhyu49e where it is "promoted" but I suspect that being a Kiwi I could bang one out of a bit of stainless steel in a couple of minutes and not have pay US$18.99 plus extortionate postage and harrowing questions and interrogations from Customs followed by a 500 odd km drive to collect it from Jaffasville airport because NZ post, despite claiming a drop in business .. do not want to deliver a small piece of flat metal resembling a book mark, to Wanganui, without an H.

Well, may they rot in hell as they are not providing a service.

For those of you who have purchased a Sulun Tac 12, I suspect you will be disappointed with the 13 page “Operating Instruction” booklet supplied with the shotgun.


I was and here is a link and after wandering the internet can now suggest a link

to a 50 page PDF copy of the “Owner’s Manual” for the Benelli M4 Super 90.

As Sulun claim that the Tac 12 is identical to the Benelli M4 apart from the stock, I am sure that you will find the Benelli “Owners’s Manual” of more assistance than the Sulun “Operating Instruction” Booklet and I suggest you download a PDF copy before the link ceases to operate.
