De-grease Armsan a612?


Tomo-1

Recommended Posts

Hi everyone.

I took my brand new Armsan a612 (in sexy realtree timber) out to the clay ground to get used to it on Saturday, as it's my first ever semi-auto.

After reading various forum posts I was expecting a few non cycles and ejection jams as we are allowed to load only 28g 7.5's.

I was not disappointed....lots of non ejectors and non cycles, 90 degree ejection jams too!

A previous post mentioned de-greasing the working mechanism. What de-greaser should I use? Any other tips please?

Apart from this minor irritation which I was expecting I found the gun to be spot on. Cast LOP etc is the same as my game gun,

so any misses were down to me and not the gun. I was using the open choke, so will try the modified next time. Thanks.

1. Get some kitchen role and any gun cleaner or even (if you're feeling rebelious) wd40.

2. Strip the gun. Clean it the normal fashion.

3. Oftwn overlooked -wipe working parts over with oily rag.

4. Put back together.

5. Go to the clay range and bang 200 odd carts through it. It will bed in easily and quite quickly.

6. Wonder why you don't use wd40 more.

I would love to be able to put 250 heavy cartridges through it at the clay ground, but would be kicked off!

To put a lot of cartridges through is going to take an age if I take it fowling but not so long pigeon shooting.

The clay ground is probably still the best option.

Be careful when first cleaning any non top of the range gun for the first time. I once got a very nasty cut into the joint of my index finger cleaning grease out of the choke housing of one of the brand new Baikal OU ejectors.

 

A sliver of razor sharp swarf was still attached and as I cleaned I suddenly noticed that the grease had gotten much thinner. Then I noticed blood peeing out of the breech end of the gun, and decided something wasnt quite right here. It took weeks to heal.

I think you will find out it is the cartridges you are using, there is a common misconception that semi autos need 28 gram cartridges to work. The load weight is fairly irrelavent it is far more to do with the pressure developed during combustion. For instañce Hull super fast 27 gram cartridges develop a much higher pressure than Fiocci top one 28 gram cartridges so you should find by simply changing the cartridge you are using will overcome your issues. I have an Armsan 612 myself and have put at least 1500 hull super fasts through it with not one failure but other softer shells cause the symptoms you describe. You don't have to use super fasts that is just the one I use as they are readily available and cheap. I find that express English spotter also have a fair old punch so they would probably be OK also. I think the best way forward is to find what shells others are using in there 612s and try them for yourself. By the way I use GT85 to lube and clean the gun so no nasty oily residue to deal with either.

Don't think it will jam with wildfowling loads. It's the lighter clay loads they tend to jam with until fully cleaned and lubed. My Beretta semi auto will not run clay loads dry until it gets warmed up so it always gets the slide rails re oiled before an outing to clay ground. When going fowling I don't bother as I run dry lube on it.

What cartridges did you use?

 

I ran my Beretta semi in with Gamebore Black Gold cartridges. They were the punchiest 28g load I could get and they loosened up the action nicely. I have since acquired an Armsan A612 for wildfowling and found it cycled those horrible English Sporter things without issue from the outset.

 

A punchy 28g load will work the action easily as well as a regular 32g.

Thanks for all of your answers, now this is probably a daft question but here goes; how are you supposed to tell which 28g load is "punchy" or "high pressure?" without actually trying a box? I thought the load was in direct relation to the amount of propellant powder. The only difference I can see on a box of cartridges, is if it's normal or high velocity/fast. Is it just a case of different companies using slightly different ingredients? Thanks.

Stick some game cartridges through it. 32g 6. If it's gas operated a tighter choke will cause it to work harder,as it will create more pressure

The op has already stated he is not able to do that.

 

Regarding punchy loads as already stated Hull Super fast 27 gram and Express English Sporter are punchy and someone in this post said black gold just Google the cartridges available to you and read the reviews.

Ok,and just put a tighter choke in to up the pressure causing the action to work harder.

Update: been out a few times since my last post. Put 100 white gold 28grm through it today on the clays...faultless. Just goes to show that not all cartridges are created equal!

Thanks for all of your replies, very helpful. This really is a great forum when we can learn from one another. Cheers.

As said above, i used hull superfast 27g in mine with no problem at all and clear pigeon 32g for crows and pigeons.

Bought one a few months back, have put exactly the same carts through it as above with absolutely no issues. Not one jam.

 

Glad it's working out well for you. For the money I just can't see where you can see can go wrong!

I agree. I also increased the choke slightly; up to Modified as suggested by PW members and my shooting instructor.

 

I have yet to shoot any pigeons ducks or geese. Not through lack of trying. Just not seen any!

 

From my limited knowledge of semi-autos it seems that you get alot of gun for your money.
