Air Arms S400 Classic(.177) - How do you guys like these guns?

Are the shrouded versions very quiet? How do the triggers compare to say a Rekord, CD, Theoben Mark 4 or BSA PCP's units?

How many shots are you getting per fill with say less than a 30fps extreme spread? Do you like how your guns balance for off hand shooting?

Regards,

Tony

AA400

Tony, I have a Classic HRB but it is 22 so I can't comment on how quiet a 177 is but I can tell you that the trigger can be adjusted to where it is atleist as good as a Rekord and better than the one BSA Hornet that I have shot. I can't comment on the shot count either as 177 would not be the same as a 22. The balance and handleing is superb and it is a great offhand shooter. If AA would make a 400/410 Classic with adjustable power in 177 I would buy one today. This is my opinion and I am sure others may differ but I have Air Rifles that cost almost tripple the price and I think AA is a real bargain in todays price world.

Thanks Joe, I appreciate the feedback, that's

good to know that the trigger is on par if not better than my favorites! Good to know it balances nicely off hand as well.

How many "good shots" do you get per fill?

Regards,

Tony

Yes it did Adam, 3rd place with a larger Air Tube added, asaik, the world's gun

February 22 2007, 2:17 PM 

had a larger air cylinder, 520 mm or so, which I believe is the current ERB's Air Cylinder which measures in at 530 mm or so...

Air Arms has yet to let me down Adam...I only get disappointed when guns fail or shoot all over the place when I am not at primary fault, lol...

Hoping to get my FX sorted out or shipped back with a quickness...may have to throw a tarp on my shooting chair now that the rain stopped briefly to see what I can print on paper with that gun...

How are the sound levels on your S400?

Any dislikes?

Regards,

Tony

I have the AA410erb

Shooting .177 JSB heavies at 850fps it's plenty quiet the only thing I here the ping in the air tube.

I get 30 shots with a max spread of 22fps.




Their are no problems, just opportunities for a solution.

Thanks for the feedback Bill, that

February 22 2007, 3:23 PM 

is good info., have you tried shooting it at 12fpe and chronied it?

How do you like the balance of your gun? My understanding is that the ERB only has a longer air tube and shroud than a classic and that it's longer air tube & shroud does not alter the balance and feel of the gun when shouldered compared to a classic...

I have never seen or held an S400 in person so am very unfamiliar...

Regards,

Tony

It balances really well I use my in a kinda informal 10m match every Saturday

February 22 2007, 4:33 PM 

It seems to balance real well with my shooting glove right on the aluminum ring where the pressure gauge is this is just in front of the trigger guard. I have the walnut thumbhole stock.

I haven't turned it that low I am sure it would help the shot count, right now I have it turned down to just a bit under half power.

Still can't out shoot it.

February 22 2007, 3:46 PM 

I've had an S-400 Extra FAC for about 5 years. I had to to detune mine as it shot 990 with CPH's out of the box. Very economical on air. It likes about 2200-2300 for its highest out put. At 55 yards I really don't see a p.o.i. change for about 28-30 shots at the 20 ft/lb level. The AirArms trigger is about as good a trigger that you'll find stock on a sporter style gun. Way ahead of the older Rapid triggers. All of the Rapid triggers I've fired lately are on AZ tuned Theobens. Don't be to in love with a 30 fps extreme spread. I did a lot of testing and did see my long distance groups open even shoot as far down as 50-60 fps below my peak of 926 fps. I was shooting over a chrony from a field target position. I was easily hitting a 1.25 flipper target in light winds again and again with CPH's even as lows as 860 fps.

My S400 ERB is quiet

February 23 2007, 12:16 AM 

at mid power setting its quite at wide open a bit louder but not much and at low its almost non existant over the hammer valve ping and pellet smacking the target. My neighbor says it sounds like wood on wood sound but all he is hearing is the impact and plywood rattling against the dog house, I shoot out of a enclosed patio thru a open door to get at least a 20 yard shot.

This is my first PCP but compared to the others I have heard it is very quiet overall and a few club guys even mentioned how quiet it was when they heard it. No crack at all really and much quieter than the RWS Mod 45 & 48 I had years ago.

Still waiting to chrony it but I have been filling to the max and getting 60+ shots at mid power before noticing any POI drop, usually by then it is down to aroud 100 BAR on the rifle cylinder gauge.

I read many people saying the sweet spot for the S400 is around 175 to 190 BAR fills yielding around 30 or so quality shots with the least spread. On a UK forum I see some only charge to 145-150 not sure if that has to do with it being a different cylinder or what but seems low to me for getting many shots off.

As for the trigger I am getting used to it like any other trigger. Lots of take up travel in the 1st stage but you can cleanly feel the 2nd stage engage and from there it is crisp, breaks fairly smooth. Pretty good for being stock. I have not tried to adjust any of the factory trigger settings yet but I may adjust the weight other than that the 2nd stage is distinct enough to feel that the long travel getting there is not a big deal to me. My Steyr M9 has a total length of pull that is only 1/8", now that takes some getting used to!

Anyway so far I am happy and shooting away. More to come as I have info to post in the future.
