Hi Guys,
Article as promised.
Pellet penetration
A comment was passed on
www.airgunbbs.com about the power or lack of it of Umarex pistols. I have the Smith & Wessson 686 (8” barrel) and I promised the poster that I would pot a few steel cans as a test.
Now it wont be much of a test without some form of comparison so I also used two types of pellet, lead and tin, to see if other comments I had heard about the tin stuff (They go straight enough but the bloody things don’t stop) were true.
The results? You judge.
First up was my Webley & Scott Hurricane .22. I put an inch of water in the cans to keep them still and fired several of each type of pellet at them from a measured 25 feet. I wanted to get some kind of effect like hitting a prey animal where the target is not held rigid and it can move simulating the action of hitting a prey target which will be knocked sideways by the strike.
Each time I got a clean hit on the sides of the can I flipped it over and put a sizeable dent in the side. This only proved that neither pellet would penetrate the can and gave me no effective comparison. So I turned the cans on their side and shot at the bottoms.

This is the most rigid part of the can and again the pellets failed to penetrate but the Dynamic Sn2 (on the left) left a better, more sharply defined dent than the Air Arms Field. Both dents are the same depth and this puzzled me until I realised that they SHOULD be the same depth since the same amount of energy. (3.2ft/lb) had been used to make them.
I should point out that I don’t have a chrono so I am using the quoted power output here and in all powers statements.
Next up was my Webley & Scott Nemesis .177 and since it has the same quoted power output this should be a good comparison. Things were very different. The first shot penetrated the side but left the tin upright with either the Accupel Domed or the Dynamic PPP1 and put sizeable dents in the other side.

The PPP1 also made a Cleaner hole with less denting round it. The Accupel is on the left and the Dynamic on the right in side and bottom pictures.

Again less deformation around the Dynamic hole.
The next test was the Smith & Wesson. I have no idea what the power output is since the manufacturer only quotes a speed without the pellet weight being given so I can not work out the muzzle energy. This minor drawback did not stop the Smith & Wesson from joining the Nemesis in the can perforation stakes and the results with the holes and deformities around them were similar.

One startling result was the side shot on the right hand can. I tried to hit it with the double action of the Smith & Wesson and only clipped the top of it on the side facing me but the Dynamic deformed the edge of the can and then punched through the OTHER side. See Below.

So what does it all mean?
Well the Smith & Wesson can hold its own with either of the other pistols and do better than the Hurricane .22 on hard targets. The larger calibre will be more effective on prey targets due to the larger pellet transferring more energy to the target and the Dynamic pellets really need to contact a bone to get them to transfer their energy even though they are hollow point.
So in conclusion
1) I would not use a pistol on live prey except vermin at close range or in an enclosed space but the .22 calibre lead pellet would be a better choice.
2) On something like a crow or wood pigeon which has stiff feathers the Dynamic pellet will be a good choice.
3) If I am ever attacked by steel cans I will use the Dynamic .177 pellets.
4) The Smith & Wesson favourably compares with most CO2 pistols for power and accuracy.
5) If I personally want to hit things with it I need to practice with the double action.
Sorry this was a bit long but it will become an article on the site and I’m too lazy to write it up twice
