springer / pcp hybrid

[eddie666]

do you think a springer and pcp hybrid could be made ?

the spring and piston could compress the given pressure in to a chamber then that pressure would be held until the trigger is pulled ,

so you would cock the rifle , then press a button or spring release device, ( the air chamber is now full )
now you can shoot when ever you are ready to .

no need for bottles or pumps , no recoil . best of both worlds .
what do you think.

Is that not essentially a single stroke pneumatic that you have described?

i was thinking of more in the line of a conversion or add on kit for springers.

Single stroke pnuematics are fine in pistol format but dont create enough energy for 12 fb rifles, i get what use say about a hybrid though.you would cock the spring and fire it off buf instead of shooting the pellet it would charge a cylinder which could be used pcp style

It would be unnecessarily complicated with two trigger mechanisms. Compression ignition in the reservoir might make things a little hairy. Interesting idea though.
Simple is always best

Cqan't imagine what it would look like or be like to lug around. As someone else said the single stroke pneumatic exists and you have to ask why no one has gone further commercially.

Webley managed it with the prototype Paradigm, I've heard a rumour that the Paradigm is going to be manufactured after all, by the Chinese.

how big is the air chamber in a pcp ? the chamber that shoots the pellet out,
would some thing small fit within the top end of a springers piston chamber to hold the compressed air and you could make the piston a short stroke to accommodate it,
iam not sure how big the pcp air chambers are and what pressure would have to be in there,
it would only take up about the space of a piston seal volume ?????

You've got me a bit confused here Eddie.

You cock the springer, then fire it to charge a chamber, then shoot off the air in the chamber to fire the pellet.

Why not just cock to charge the chamber and then shoot off the air in the chamber to fire the pellet. Just like an SSP does. I don't understand putting another sequence in.

cocking would not produce the pressure needed , it will need a good wack of spring to compress the air to get the pressure needed to produce 11-12fpe
i have found that the seals are made to have ( blow by) its only the speed of the spring that makes the pressure, thats why an old worn seal will still work if you add more washers to increase the springs tension .

also if there was no ( blow by ) and the way the seal is designed it would take you ages to cock the rifle as it would have to suck all the air back in the chamber through the port hole, this is also to help the spring to keep mowing forwards and smooth as it ties to push air through the port hole and push the pellet down the barrel , its like an over flow system , the more power you put on the spring the the harder it is for the blow by to work as the seal will flair out tighter and let less air pass behind it , this will give you more recoil and a harsher shot and a longer time in a stroke, now you know why spring grease can get in your chamber.
