OK, so I took it out to the field for about 8 games, and I really like the way it shoots. The velocity was still all over the place, fluctuating from 250's to 280's with mid-grade field paint. The thing is so loud compared to my pump Nightkast, but that's OK as long as it's not a symptom of a problem.
I'm also wondering, did I buy an old STP or did someone sell me a Bronze and call it an STP. Most of what I've seen lists the bronze as non-milled body, right feed, and not externally adjustable. Did I get rooked?
Either way, I hope to get this to PPS for some wedgits and valve job at least. Any recommendations you guys could give on tuning this to make it a little quieter?
