I really like the low budget trick for pressurizing the tube.Btw, a 2400 won't work with a tank block unless you replace the tube with one for a 2260. That's what you have to do if you want the forend. The other option (sans forend) is to get a 2300 instead, because it is basically a CCS 2240. The longest barrel available on them is 14.6", so you would have to replace the barrel if you wanted it longer.A better starting point would be the 2400KT from the Crosman custom shop, it would even be cheaper as Jason and i discussed earlier in the thread.The 2400KT is the one I was referring to. A 2300KT is easier to add a bottle.Quote from: nervoustrigger on August 02, 2016, 01:23:18 AMCan you fill me in on what it is about the 2400 tube that won't allow it to be pressurized? I'm seriously considering building another, this time holding to the goals I originally set out and the 2400 otherwise looks like a good starting point.It's not that the 2400KT tube can't be pressurized; there's not enough tube beyond the barrel band to remove the threaded portion, and the forend makes it difficult to relocate the band.

I needed a little shooting therapy after work this evening so I grabbed a bunch of different tins off the shelf and did some pellet testing at 25 yards. Overall it appears to not be very pellet picky and rather tame considering the unsupported length of the barrel. The sub-MoA groups are highlighted green, the very best of which was 0.5 MoA.

The 2400KT is basically a custom shop 2240 with a forearm and stock, and this whole thread is a about a bottle PCP that nervoustrigger made from a 2240. The forearm is only attached by a 2250 barrel band on the 2400KT. That comes off just like a standard barrel band.
JSB seems the way, yeah?
Wow! That is some great grouping! This is still with the factory barrel?

That is some great grouping! This is still with the factory barrel? Thank you! Those groups were shot with the forestock rested on a pedestal but the buttstock shouldered, so not quite as steady as shooting off a table with bags. So yeah, I was pretty happy with some of those. The barrel isn't the stock shorty .22 cal but it is a Crosman barrel...a .177 Discovery barrel #1760SE-001 which has been the recipient of the usual barrel prep.
