RTI Prophet Compact Performance .22cal: Plenum + Tuning + Power + Bottle Do you know what to do when you bought a gun — but it hasn't been delivered yet? ➔ Yupp, you can shoot it in your mind, tune it in your mind, set up a new Strelok file, gather the ammo for the first day of testing, clear a spot to store it, order o-rings, aftermarket performance parts, accessories....
OR: Pester your fellow forum members with questions!
➔ I've done the above. Stopped short of selling a kidney to pay for it all.
Now it's time to get on the forums....! Before you answer any or all of my questions (simply refer to the number) — I want to make sure we're all on the same page:
●
I only have a CF tank, and I can't drive clear across town to get it refilled (because my town is the size of a country, 10 million+).
Therefore, my average pressure I can put into the gun's airtube is mostly going to be less than 300bar.
➔ Average pressure available in my bottle I'd say is going to be 250bar. ●
I'm looking for this tune in .22cal: • 33-36FPE
• 18.13gr to 18.5gr pellets
• 900 to 950fps MV
• I'll play with slugs as well
• 5 to 100 yards
• I want to do pellet BC testing, which requires frequent power setting changes
• • • • • • •
Q1 • Extended plenum: By how much would I increase my
shot count (ballpark figure)? (this is the
Compact Performance version, and I assume 250bar in the bottle)
Q2 • Extended plenum: I am somewhat concerned for
a quiet tune — i.e., rather shorter sips of air at higher pressure — than longer gulps of air at lower pressure.
Would the ext. plenum favor that kind of quiet tune — in the
Compact Prophet — or does it move me into louder?
Q3 • Extended plenum: Any other advantages or disadvantages of using the ext. plenum?
Q4 • Regulator adjusting: What are the proper steps to change the regulator setting — not to mess things up? (This is my first gun with external adjustment.)
Q5 • Larger bottle: What options are out there to use a larger bottle on the Compact? (price, link?) (The bottle must not hinder the use of a large DFL silencer.)
Q6 • Other advice: Do you have any other recommendations for me?
Thank you all!
