Cannon Special 737

This is a pump up pneumatic air rifle, and is made in Indonesia. Mine is .177. I believe it gives around 600fps at 3 pumps, and 800 at 6 pumps, and 1000 at 10 pumps, so you don't get too much more for your effort at 10 pumps, although anything more than 8 pumps and it sounds a bit like a 22 rimfire, making a loud "crack". Don't give it more than 10 pumps, as the heat generated by the high pressure can melt the seals. 8 pumps is sufficient to kill a possum or rabbit at about 20 meters with a head-shot.

I have found no way to change the trigger weight as mentioned in another review. In fact you'll notice the trigger weight increase as you give it more pumps. There is no crisp release, more like a long drag, but once you know what to expect, it's ok. Loading the pellet can be a bit fiddly, but after a few hundred shots, not a problem.

At first the gun is difficult to pump (especially after about 4), but once you've worked out a good technique, it's not too hard to give it 10 pumps (but still difficult!). 3 pumps is fine for plinking. 1 pump is enough to penetrate a coke can.

Accuracy was reasonable, I was able to get about a 2cm radius group at 20 meter. At first I thought that changing the number of pumps affected the accuracy, but in the end this seemed to have no effect. Occasionally I would get a pellet land about 4cm away from the rest of the group. Was using Gamo Match pellets, and haven't had a chance to try others. Let me know if you find a more accurate pellet.

Finish is good, a fair amount of plastic thoughout (trigger, trigger guard, front and rear sites, receiver, and barrel cover). Plastic barrel cover protects a brass barrel, I'm told this is better than normal metal barrel, as it provides less friction for the pellet. Because the brass is softer than steel, you should use lead pellets only. Although there is a lot of plastic, the gun feels reasonably robust, and I didn't have any reliability problems. Wood finish is good.

An advantage of the rifle being a pump up rather than a springer, is you don't need a special scope and scope mounts, and I purchased it with 4x28 scope. Another advantage is light weight and size (2.1kg, 88cm).

  The most powerful pump gun I've ever heard of is the Benjiman or Sheridan Blue/Silver Streak models. They shoot max fps of 625 in .22 cal, 675 in .20 and 800 in .177. I've never known of a pump gun that gets even close to 1000 fps in any caliber. Try shooting it through a chronograph. Bet your going to get something like 700 to 750 fps. Even the Benjiman .177 cal that's rated at 800 fps will only get that with ultra light 6.5 grain pellets. The average pellet purchased off the shelf is about 7.5 to 8.5 grains. This will slow the 800 fps gun down to about 675-725 fps. Even the spring guns rated at 1000 fps dont get that except with 6.5 grain pellets and thats only for the first 250 shots or so. Once the gun is broken in it loses 8 to 10 pecent of it's power pulling it's velocity down to 900 - 920 fps. Throw in an average weight pellet of 7.8 grains and this goes down to about 820 to 850 fps. If your gun actually shoots even near to 1000 fps. then you truly have an awsomely powerfull pump gun! I'm not saying that it's impossible, just highly unlikely. I am an avid air gunner. I've owned several different types of guns and have yet to ever hear of a pump gun that is anywhere close to being that powerfull.
  Want true power? Get a Gamo Hunter 1250. I have one and let me tell you! That gun ROCKS!! $375.00 will get you a gun that will break the sound barrier with 8.6 grain pellets. Thats over 1100 fps. I shoot Beeman Kodiaks 10.6 grains. They chronograph at 1050 fps and will punch through a 1 inch thick piece of wood at 25 yards. It's a spring gun not a pump, but it's worth the money. Very accurate too!
