I thought I'd refrain from mentioning I had one too.....and just let you see the top 10 anyhow!
The 100 full length will give you more shots per fill than pretty much any other PCP with the factory bottle on. 120+ in .177
Its something to think about though, if you are target shooting, I wouldn't go something like an Ultra as you will need to fill every 40 shots or so. If it is just targets, you will find PCP will be TOO EASY and you will get sick of filling it. If all you want to do is shoot targets, get a springer, more of a challenge and you will improve your shooting no end! If not,
