That borders on the unbelievable for the smallish reservoir of the rifle. I hope it's true but until Bob or someone similarly qualified chimes in, I remain skeptical.He says he used a slightly higher fill pressure so I'm guessing 1700psi. Let me stretch it to 1800psi and let's say the ending pressure was 1100psi. That means the efficiency was 1.49fpe/ci. That is stellar! But do I think the 60C breathes well enough to ring off the last shot at 885fps or 27.8fpe with "only" 1100psi behind it? Hmm...Also, that result appears to be much more than an incremental improvement over what others have reported. If he said I ported this and polished that and modified the striker, then maybe. But he says all he did was tweak the hammer spring preload.Again I hope I'm wrong but I don't want anyone to get their hopes way up." (From nervoustrigger.)
