beretta al391


Recommended Posts

don't know if its just me being stupid but ive got the beretta al391 its only a year old, and cartride picky. its been back to the dealers to be checked and returned with nothing wrong with it, but depending on the cartridges it dosent sent the carrier back all the way resulting in the cart being jamed and not reloading the second, happens with rio, eley, and some gamebores, dosent matter if the load or wad changes still does the same. could any one help.

It was the same with me at one point, I was using hull inter-comps,went through at least 2 boxes and then all of a sudden it started to jam on them or not cycle them at all.

Now I use Gamebore clear pigeon 30g 6's or I use Lyalvale Express Supreme Game 30g 6's.

Both these loads slam that carrier back into my shoulder pretty well!!!, most semi-autos dont cycle well with anything bellow 28g anyway, what cartridge weight are you using.

Sounds like it needs a complete strip down, polish and lubrication.

 

I took a mates 391 which was rusted fast, it took a while but with the beretta manual off the net and some patients it now looks and fires a dream.

 

If it won't cycle 30 or 32g loads, there is something wrong with it no matter what anyone tells you. Places to look are the exhaust port (clean, free from coking up as well as the forestock and its venting hole) as well as look for excessive friction in the action which might be caused by pitting.

 

GL mate, lovely guns, I am sure given to the right person yours will be too.

it cycles 50g 3inch magnums fine, all the exaust ports are clean and everyting is well lubed like i said before just seemed to be certain carts it dosen't like for instance it hates country club carts loaded by eley which are 30grm loads but if fine with 30grm loaded gamebore clear pigeon fibe wad. just wondering if its the powder that the carts are loaded with.

bunny i am using a 391 as well no probs atall with any cartridge i have put through it ,mine is not spanking clean either ,i have dropped to 28gram loads with no probs .

these do have a variable exhaust port on them wondering if that is set right ?

I had problems with black gold 28g cartridges but the 24g and other 28's seemed to cycle fine. I think that if you allow the gun to recoil ie don't have a good grip or let your shoulder get "pushed back" as the gun fires the action doesn't have the momentum to completely cycle the round.

 

I used to have pistols that did the same if allowed your arms to absorb some of the energy.

 

Were the jams after a prolonged shoot?

Chop it in for a Bennelli - No need to worry about keeping the ports etc clean, as they don't have any !! :)

I've got a 391 and shortly after I bought it (new) it started to misfeed.

 

This was traced to the long recoil spring in the butt (which the carrier pushes back) being bone dry of any lubricant.

 

Strip the gun and depress this spring with a rimmy cleaning rod or similar. Then put a small amount of gun oil on this spring or on the walls of the tube in which the spring operates..

 

Worked for mine - it now fires anything from 28g upwards with no problems.

my old man has a 391 i use occasionally, its been cleaned about 2x in 2.5 yrs, i can count the number of malfunctions on one hand.

 

it will feed most cartridges, but low recoil carts wont work (chevrons) its been faultless, never been maintained other than a quick lick of beretta oil and clean barrel.

you could always try boring the ports out very slightly. a mate of mine done it to good effect but id check with a gun smith how much you should drill them out. also make sure everything is lubed up well.

If you bore out the ports you get lower pressure so it may not work correctly also it would have to be lapped out or you could have small bits of swarf in the berrel edge and remember that you cant put metal back.

ya i know what your getting at the sa80 and LSW have an option on the gas parts, for when the wepon has be use for a long time with no cleaning. So when the wepon miss loads sevral times, you turn the gas parts to get a clean hole and on closer inspection the hole is slightly larger.

Never had a single problem with my 391.....I think it is superb.....I have saw a semi not eject the spent cartridge properly when the shooter has not had a firm grip on the shotty(a rather snassy camo webley). Moved away from him rather sharpish (not comfortable next to someone who can't even hold a gun properly).

 

maybe you should stop keeping your after shoot beer money lodged in the end of the barrel.
