Beeman P22 Project

Unread postAuthor: jackssmirkingrevenge » Fri Mar 31, 2017 8:48 am

Got myself one of these, the cheap and cheerful variation of the HW 40 PCA made of the finest Chineseium. Shoots about 410 fps with a 7.8 grain Daisy flatheads, very pleasant.


Image

Naturally I took it apart :D the plan is to convert it to 0.22" and have it shooting as close to 500 fps as I can manage.

Image

Look at that tiny transfer port, just 2.5mm diameter - less than a third of the cross-section of a 4.5mm barrel in terms of area, shameful.

Image

The valve is of an unusual design in that it is pulled rather than pushed open, and is already somewhat balanced, but there is always room for improvement.

Image

Original barrel alongside an externally battered but internally clean Crosman 2240 barrel I obtained, will probably keep most of the length and cover the excess with a faux suppressor.

They are surprisingly good for the dollars spent. Not a power house, but fun and fairly accurate. :)

Any reason to switch over to .22 caliber? Will the longer barrel/heavier pellet create less noise? I've had a beeman p17 for a while now, but shooting it in my backyard is kinda noisy.

Given the build quality I'm honestly amazed at how little they go for.

Not a power house


Give me time :D seriously though if I can have it shooting .22 at the same velocity it was shooting .177 I'll be happy man.

The same as it ever was - MOAR POWER! I'm not a paper puncher, prefer making holes in stuff, and .22 does more damage.

For the same volume of air, it should give greater volume for expansion and cut down a little on noise with all else being equal.
