amazing engineering skills but not a fan of c02 in otago, gets to cold and then it's useless]]> Mon, 15 Jun 2026 20:49:36 +0000 www.kiwiairgunners.co.nz/forum_posts.asp?TID=1341&PID=14672#14672 Pauly's Technical Area : .25 CO2 beast www.kiwiairgunners.co.nz/forum_posts.asp?TID=1341&PID=14668#14668 Author: Mintie

Keen to see how this turns out, ive done a few .25 CO2 builds over the years but only with standard sized valves that I have hogged out for more volume, will be interesting to see what sort of power you can get out of a full custom valve!

From memory one of the Crosman builds I called the 2540 got about 16 fpe from a 10" barrel, and the 25cal CR600 i built for Zooboy got about 22fpe from a 20" barrel. Both of those just ran on 12gr cartridges. ]]> Sun, 14 Jun 2026 15:17:06 +0000 www.kiwiairgunners.co.nz/forum_posts.asp?TID=1341&PID=14668#14668 Pauly's Technical Area : .25 CO2 beast www.kiwiairgunners.co.nz/forum_posts.asp?TID=1341&PID=14665#14665 Author: RangerPete

Nunga, the big question is does your new trigger SMELL like beer???]]> Sun, 14 Jun 2026 14:44:16 +0000 www.kiwiairgunners.co.nz/forum_posts.asp?TID=1341&PID=14665#14665 Pauly's Technical Area : .25 CO2 beast www.kiwiairgunners.co.nz/forum_posts.asp?TID=1341&PID=14657#14657 Author: J-S

I love seeing custom builds. Following this build with interest.

CO2 is well capable of 30 ft-lbs in .25 and it may use less gas than expected.
e.g. I got 26 ft-lbs in .35 from a 6" barrel and it used 1.1 grams per shot.

You should share some of your builds here!

Speaking of mods. Has anyone ever tried one of these in a co2 gun? Just wondering if it would actually work if I was to buy a co2 gun and use this instead of buying the disposable ones.

I just found this on AliExpress: | Outdoor Inflation Reusable gas Tank Tire Inflator Stainless Steel Mini Pump 8/12/16g Co2 Cartridge MTB Bicycle Bike Accessories

Trigger is made from recycled beer cans. I melt them down in my big furnace into ingots. That is a leftover bit from my melt.

So the trigger is made of beer! Beer

You could buy yourself a benchtop lathe. That'd open up another slippery slide to fall into. :)
