Leak fixed...Something I forgot to check... I was curious if the TP has the same ID in .177 and .22. I do know that I left the .177 TP in the Varmint and I just got 21 consistent shots from 2900 down to 2100 psi. 3 mags is plenty for a morning in the woods. I could probably get another mag if I filled to 3100 ish down to 1900 ish. This gun shot it's best between 2900 and 2100 in .177. I'm assuming that is still the case and I'm good with it. I was getting almost 4 9 shot mags when it was .177. Interesting to see what the CP-2 will get with the long barrel and in .177 now. That's a story to be told after breakfast......Notice the grin so far?
