No problem digging up an old post.

It's averaging around 580fps at 18°C and with JSB Straton 15.89gr pellets.

I prefer the cr600 over the 2250 for accuracy and if I'm setting up for a while plinking or pest controlling. I've now got bipod on it too.

2250 is better for spot and stalking being lighter and more maneuverable.

If you want me to pop in sometime after work with the cr600 for you to have a play let me know. Got a leak in the 2250 so its in bits again.

Took another 3 starlings over the weekend but there are 1000's of them flocking on the paddocks at the moment.

I've stretched it out to 40m but waiting for a new scope to turn up to fully ballistic calculate the range.


I know it has been a year since the last post on this thread but would love to knowthe results of your mods and if you made any further modifications? Seriously considering a CR600 but would like a bit more power than standard, to fit a bipod and perhaps a 24gram co2 bottle which can be filled and used in place of the 12g co2 canisters. Either that or a 2250b or 1322 to modify as I see you have also done.
Which is your preferred rifle, the CR600 or 2250?

Is drilling out to 4mm straightforward, or do I run a high risk of ruining a brand new rifle and voiding the warranty?  I don't personally have many tools but the people I'm stating with have an overflowing workshop. Trouble is it is litterally overflowing so finding a specific tool is a challenge.

Cheers

nice mate,these are great little co2 rifles and do allso come as pcps,so will make an excellent hpa conversion,just a word of warning for those without firearms licence,that once converted to hpa this rifle then legally becomes a pcp rifle,but for those with licence the hpa conversion is the way to go as it can quite significantly increase the power out put if wanted,nice job on rifle sounds like those starlings taking a hammering from it too.

Good evening all,

Thought I should share my latest custom build I've done to a CR600w.

Picked this little beauty up recently and used it for my annual starling shoot around the house. somewhere the tally on starlings from this rifle is around 30 over the last month. 

This is really a brilliant rifle as is but decided to tinker. out of the box with Gun Cities .22 Javelin spear tip 15.74gr pellets I was getting an average of 508fps, I've drilled the internals out to 4.5mm and now achieving and average of 585fps. 

Next was a custom Carbon Fiber barrel shroud with an adapter to fit 1/2"x20 suppressors threads, I have fitted a Stealth .22 rimfire suppressor which does make it a little quieter than the factory one. 

Also I've made a bulk co2 adapter which has a quick release fitting for a 9oz paintball tank for more accurate shot strings. I do have a HPA tank to try through this running 1500psi at the regulator. 

See photos below.
