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.

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.
