Just something crazy to do for a change

Nope the Benji is a break barrel!!!! I ordered a .22 from Air Gun Depot to replace the .25 I returned and it is also a break barrel and it is advertised at 1200. Everybody knows they inflate those numbers 10-15% but that is still packing a mighty hard whack when they get there. A fellow did the Chrono test and was getting an average of 25 foot pounds of muzzle energy so that aint too shabby at all. The whole swap ended up costing me the price of 2 tins of ammo. They could not return the ammo tins I had used some from but they allowed me to return the one container I had not used any of, soo I bough a tin of match grade dome top and another of match grade hollow points. Both of them are 14.3 Grains and should do around 24 foot pounds of energy. That gun also has a three year warranty which is three times what everybody else is offering. Go to Air Gun Depot and have a look at the Umarex Octane. The specs are pretty darn interesting even though we know that they are over stated. All of the manufacturers do that so it is a pretty common 10-15% boost they give the numbers so I just multiply their number by .85 and see fi it is within the range I am looking for. Unfortunately since it was delayed for a day arriving in Salt Lake it will not arrive this Saturday as I had originally planned. Looks like it will arrive Monday or Tuesday at the latest. Either way they have paid the freight on everything going both ways so I am very happy with the service and the people are really helpful and have actually used the merchandise so they at least have a clue when you tell them about some issue. When I explained the trigger issue they really switched gears and wanted that gun back as quickly as they could get it so they must be having to extend the recall to include more serial numbers since mine had a relatively new number. Have a great night!!!!

o.K.,I went to the Depot site. The Benjamin I could find in .22 cal. at 1200 FPS is the XL1100(or is that 1100 fps?) Anyhow, WHAT is a nitrogen piston? Is the gun still a break barrel? I THINK it is,as a force of 47 pounds to cock a gun is mentioned.

So,WHAT is a nitrogen piston? I am not up on all this new stuff,only having collected really old air guns(Except for the Kodiak). An explanation would be appreciated.

P.S. It seems they all need replacement triggers. Who is this Charlie daTuna?

I am sure that as many of you already know Lewis and Clark took an air rifle with them on their expedition. If I remember correctly it shot 38 caliber rounds and up to around 30 before reloads.
A friend of mine sent me this following link, this guy is making one very similar with todays technology in
9 MM.

the Lewis and Clark expedition was in 1804

Yes,they impressed the indians with their air gun because it made no noise.

We had an 18th. C. air rifle in the Gunsmith's Shop in Williamsburg,where I worked as toolmaker. It was made more nicely than most real firearms(they HAD to be to hold compressed air). This one had the copper ball underneath. Some even used a flint in their hammers,and you put gunpowder in their pans to make the locks flash realistically. These guns cost more than normal fire arms.

Napoleon's army,or the Austrians had some snipers with high powered air rifles with cast iron flask butt stocks. They were deadly. They were pumped up with engines that looked like fire engines. The British considered it a capitol offense if they caught a soldier with one of these guns. They were considered sneaky and unsportsmanlike.

I will mention that the ancient Greeks had catapults that operated with a pair of large syringes. They used the power of the compressed air to operate a bow to shoot projectiles. I wonder how they kept them from leaking? Probably had to shoot soon after cocking.

Great to see an interest in air rifles starting to grow. I have been active in controlling pests with air rifles for years and have even taken birds at 80 meters with headshots. They are usually underestimated.

Just be aware that the velocity ratings are not the measurement for power, ftlbs or joules is. Many figures use the lightest grain pellets and chrono the projectile right at the barrel.

Pellet selection is critical and so far, I am yet to find anything better than JSB exact pellets. They have excellent quality control and the ballistic coefficient is much higher for than for other pellets, meaning they retain their energy further from the rifle.

Most people like velocity because it means that there is less compensation needed for holdover. The flipside is the lighter pellets that shoot flatter run out of steam much faster and are much less suited to hunting. My .22 uses 16 gr pellets and my .25 uses 20 gr - 24 gr.

Exactly,Sam. Those light pellets run out of steam quickly.
