Yes they are fun little guns for sure. My .177 ended up being so accurate that it compelled me to scope it. I just felt like I was squandering its potential with anything less. Tuned to a modest 560fps with the 9.3gr RWS Supermag wadcutters (6.5fpe), it will reliably put them in dime at 25 – 30 yards. On a calm day, anyhow.
A word of caution though. The regulator is among the most persnickety I’ve ever dealt with. For some people it works great but quite a few have thrown their hands up and installed a Huma. Assuming yours is currently working well, be advised there seems to be a good chance it will start acting up when the day comes that you have to open it up and replace an O-ring. The culprit appears to be the white plastic disc that serves a dual role as a seal and the valve seat. Frequently it will either leak or creep (or both) after reassembly. There’s a detailed fix posted on GTA titled “PP700SA regulator fix” if you want to familiarize yourself with it.
Meanwhile have fun with it!
