I received subject rifle a few days ago and wanted to provide a quick preliminary assessment.

Specs:
MAKE/MODEL: Benjamin, Model BT725WNP; Retail price about $300; ammo price $3.00 for 200 pellets (makes for economical shooting).
CALIBER: .25, pellet weight 31.5 grains.
STOCK: Nicely finished American hardwood with thumbhole, pressed checkering at forend and pistol grip, quality buttplate, nicely fitted white spacers at butt and pistol grip. Has sling swivels fitted and sling.
BARREL: Bull barrel approx 19" in length and thinner where it attaches to the 'chamber' and tilt/cocking mechanism.
SIGHTS: Scope only, comes with Centerpoint 3-9 x 40 scope which must be user mounted to the already installed Weaver type scope rail.
PROPULSION: Nitrogen gas piston, a new one for me, takes considerably more effort to cock than my Gamo Whisper with spring piston. However, much quieter than the Gamo (which has an integral suppressor) and much less recoil.
SAFETY: Military type inside front of trigger guard. Easy to locate and activate with the trigger finger.
WEIGHT: Ten (as in 10) pounds! This is not a rifle for children or smaller ladies!

First shots: I was surprised the scope was very close to zero merely by mounting it to the scope rail. This, to me, says something positive about the manufacturer and quality control.

I set up the chrono for the first ten rounds and all measured between 910 and 930 fps. Not bad and sufficient power to go through a 5/8 sheet of plywood. Should certainly be adequate for any small game. The pellets grouped at about 3/4 inch at 15 yards. The manual states accuracy will steadily improve during the first 100 or so rounds of 'break in' so we shall see what we shall see. The trigger pull is about 4.5 pounds, vastly better than my Gamo which must be 12 lbs plus.

Overall impression: I'm pleased. A nicely made and fitted rifle with a decent scope. So far it functions flawlessly although it's somewhat of a muscle builder to cock. The best technique I've so far come up with is to rest the butt in my left hip area, pull back on the stock forend with my left hand while pushing the muzzle end of the barrel down with my right or shooting hand. If you're a lefty, reverse the process. Another method is to grip the stock butt between your legs, 'break' the barrel part way down, and then use both hands to cock. Either way some effort is involved.

I can shoot out to a couple of hundred yards on my property so I'll come in again with a long range assessment in a few weeks,
 
I've always loved various types of "air" weapons since my first Red Ryder BB gun back in the 50s. Had lots; various BB and pellet models including a Benjamin .22 pneumatic that I put many thousands of rounds through. I credit that gun for my qualifying as "expert" with the M-14 in basic training.....
Currently, I'm going the opposite direction. Since I love making things, I've been working on a home-made air gun.
There's a small community of folks experimenting with various sorts of these things, from very crude to amazingly sophisticated.
Mine has arrived at test-bed stage; using a spring-operated ball valve to dump a 125psi charge into the 1/2" tubing barrel.
Plan to build a reciprocating-valve model.
There's plenty of info on these on YouTube.
 
That is a very powerful air gun , thanks for the review C4. I have a 30 year old BSA Airsporter in .22 that is nowhere near as powerful as your gun and I had no problems killing rabbits at 50 yards. You should be able to hunt to 100 yards with ease.

Thanks for the review Old CW4. I'm currently in the market for a good air rifle and was having a hard time choosing between all the brands. Your Benjamin .25 Cal Nitro Piston Rifle looks like a nice rifle.

What is the performance difference between .25 and .22 caliber air rifles?
Is the advantage mostly having the ability to take larger game?

The reason I'm curious is because I've noticed .22 rifles are less expensive and the pellets are easier to find in stores.
 
NorCalMtn2,

I've never shot a 22 pellet gun but have read some good things about them. Since the 25 is a tad heavier, even though a bit slower in velocity, I decided on that.

I'm from the side of the playground at the old school that prefers larger calibers and heavier projectiles. The same reason I went to 45-70 rifles and handguns with 450 grain bullets (in both) plus 41 and 44 mag handguns, years ago for big game hunting. When those 405 grain 45-70s hit even close to the 'boiler room' the animal goes down and right now.

Seemed to me that 900 fps plus with a 25 pellet should do the same thing on a smaller scale and make an excellent small animal stopper. The 25 pellets, BTW, look identical to a 177 pellet, just much larger.

I shot the 25 some more today and I do like the nitrogen piston concept better than a spring. I just hope it's as reliable over the long term. Supposedly, you can leave it cocked for long periods with no ill effects which is something you shouldn't do with a spring gun. It's also supposed to be more tolerant of the ambient environment with the nitro piston energy unaffected by real hot or real cold weather. Again, we shall see.
 
I think you might have a special rifle there! When I was researching that model I seem to remember folks getting ~650fps with the regular lead pellets.
 
I don't know about 'special' since I'm new to larger caliber pellet guns. I'm using Beeman (German made) 'Kodiak extra heavy pellets for long range efficiency' and I had the chrono 'triangles' about a foot from the muzzle as usual and in bright sunlight. As with projectiles fired with gunpowder there's always some variance but this rifle measured as I said, from 910 to 930 fps with the low being 910, the high was 930, and most were pretty tight at about 918 to 924. I was/am quite pleased with that.
