How did you like it compared to a 6.03mm or 6.01mm from another company?

Found this just recently:

Are these good groupings for 50 feet? If it's possible to achieve smaller groupings, how?

I like my Prometheus 6.03s with the ER-hop installed, really the best way to do this.

Those are pretty good, but almost all of my rifles can do better, and I am sure some other people on here are the same way (woogie). In fact, the only one that can't is in pieces getting fixed so that it can.

I'm really getting interested in the ER-hop up now :yup:

I just bought the penultimate part for my sniper like an hour ago so it's almost 100% upgraded internally.

Prometheus 509mm

I still have to install my PDI chamber before I can use it haha >

Once I test it thoroughly, I may ask more questions about that ER-Hop.

By the way, did you cut your 509mm barrel just so it fits in the outer barrel or for performance sakes?

What? I use the right length prometheus for the rifle, though if they are not HPA (unlimited cylinder volume) I use 455mm length, and use a barrel shroud.

BTW, I keep going on about the ER-hop, but at short range (less than/equal to 50 feet), to get amazing groups the best way is to have absurdly high fps and no hop at all.

Oh my apologies, I mixed your barrel with I believe Woogie's... or maybe it was Fuzzy's :doh: They had a 509mm and cut it down so it fit in the outer barrel.

Thinking about the logistics of the bb flight, I feel that a 6.01mm or a 6.03mm with extremely high FPS and no hop up would have almost no difference in accuracy.

That's what actually persuaded me to buy the Prometheus 6.03mm. I can use it for skirmished with lower FPS or for close quarter competition shooting at VERY high FPS.

Yep, good plan!
