Yea, it's a gas spring instead of a metal spring. There is less mass in motion and less rebound. From what I've read, the recoil pulse is shorter and snappier with the gas ram. A pneumatic by comparison has essentially no recoil and no mass in motion. All you are doing is openning a valve and letting air loose. The one thing that makes springers so darn hard to ignore for me is the sheer simplicity of cocking the barrel and shooting. While I like the shooting qualities of a precharged pneumatic much better, it is a drag dealing with the tanks, hoses, fittings, and all the other support crap that they require, not to mention the cost.

One more thing you should probably know is that the listed velocities for all airguns are determined with leadfree pellets and then fudged another 5% or so for good measure. I rifle listed as 1200fps will probably be good for about 850 in real life. I think the .22 nitro does about 650 with 16gr pellets which is till plenty for small game.

Paul Capello, guy that tests airguns for Pyramyd Air tested an NPSS, he used the 14.3 grain Exact Jumbo Express...10 shot avg. was 654 fps, with 15.2 FPE...... Like the man said, that's plenty to hunt small game with.

Is there a gun out there that will shook 1000 plus FPS with out spending $500?

packrat · Senior Member

Yes there are.....BUT only if you use that PBA ammo, and from what I 've read about it, most airgun guys give the PBA stuff "two thumbs down"If I'm not mistaken PBA weighs like 4-5 gr. so naturally higher fps 's are possible.

The 2010 Crosman Trial NP XL 1100 is boasting 30 FPE! What makes that gun different from the regular trial np? Is the gas spring stiffer? They seem to be cosmetically the same gun. I can't imagine they could give it a larger swept air volume with the same receiver can they? I was just wondering because if someone can figure out the secret they could be able to buy the Crosman Titan GP from Wal-Mart and upgrade it to a Trail NP XL 1100. There are lots of companies online that sell gas springs and if the specs of the springs can be obtained then it would not be hard to find a suitable gas spring for the mod. If the gas springs just so happened to be the same spring filled with different volumes of gas than a replacement part for the XL 1100 could be ordered and installed in a regular NPSS upgrading it right?

I have a Benjamin (Crossman correct?) Trail NP XL. It is physically a large gun. Almost 10 pounds. I am 6'5" so it is comfortable for me but some of my friends think its a little heavy. I like it a lot. When I got the gun, I only haphazardly sighted in the scope that it came with and I was able to hit beer cans 200-300 feet away with satisfactory regularity.

I tried going squirreling at my friends house and found that the supplied scope was difficult to use on moving targets with variable range. Since the bull barrel does not have front sights on it, I replaced the scope with a red dot sight from NcSTAR and it is working pretty well. I need to sight it in better though.

It seems to like heavier pellets. I found that the Beeman Kodiac / H&N Barracuda 21.14 grain domed pellets shoot the best for me at least. The 13 and 16 grain pellets seem to make the gun smoke (diesel?) pretty badly.

Pretty impressive.

Rifles like that should always be shot with heavy pellets. Light pellets cause, as you said, slow burn and dieseling. It's also not very good for your piston seal.

Not sure if I'd put a red dot on a rifle like that but if it works for you, I'm not complaining. Mr. Green

This might be a little late but Crosman NPSS is made in China the Remington NPSS is made by Crosman in NY USA. Same Gun Better made here. TFG
