I definitely realized that the air volume won't be enough for .40+BBs which is why I wanted to go with .32-.36 because I feel like they'd work pretty well with it. I'd also like to try getting my hands on the large volume CPSB cylinder and see what that does too but I can't find anywhere that sells it in the US. I'd have to order it from the ares e-shop or elsewhere overseas that isn't sold out. Likely for me there aren't any HUGE fields in my area that I'd need to push the limits on a long range platform for haha.
And yes, that is a VORSK 5.1 with TM Spec Dynamic Precision internals. Still have the stock hop up chamber though because TM Spec hop chambers are too wide. I watched a video on YouTube where I guy filed the bottom of the hop chamber and it worked, so I may they that with a cheap unit first and if it works, then I'll get a good hop chamber and do it to that.
