RTI Can the RTI Prophet 2.1 (.22) be tuned to shoot CPHPs?

[Phil.Probe]

I'm just trying to narrow down my options for my first "buy once, cry once" pcp. The RTI prophet 2.1 looks like it ticks a lot of boxes, but the newer version's .22 barrels seems to be designed around slugs more than pellets. It's looking like it can only be turned down to 40fpe, which I believe would be sending those 14.3g CPHP pellet supersonic.

However according to this review (older model with different barrel twist rate etc), it's said to shoot the CPHP with excellent accuracy as supersonic speeds.

In this RTI Prophet PCP test review, we're looking at an interesting airgun with some unusual features. It’s made by RTIArms in Slovenia.

So my question is, can the 2.1 with it's new barrel shoot CPHP's with great accuracy like it's predecessor?

I only spent a bit of time with one. I think it will be hard to tune it that low, as I tuned for 18’s and that seemed a challenge. Someone who has spent more time with one will know better. My RPB barrel in my P1 shoots pellets and slugs very well, it’s my favorite barrel! Maybe find a P1 used. Some places still have them in stock new as well.

Check the twist rate of the barrel. A barrel with a lower twist rate (1:22) will be better at shooting pellets. Converse to that, a 1:15 will be better at slugs since they need more twist.
Good luck and keep us posted!

I guess if I'm honest with myself, I don't want something that's going to be a challenge to go from one tune (low power pellets) to higher power and slugs. It's only going to be a useful feature for me if it's a 2min job to go from one state of tune to another.

I don't recall the exact numbers for twist rates, but the newer RTI designed barrel is billed as having a higher twist rate, designed to favor slugs. The older one is a different story.

My .25 cal RTI barrel shoots slugs and pellets equally well, actually a little less finicky with the pellets I have tried. I have not however tried a low power tune as that does not fit my use for the rifle. As for adjusting. For the PCP's I've owned this one is the easiest by far. Reg can be set both ways with the rifle aired up, the hammer spring doesn't need fiddled with for the sweet spot (but a few clicks on way or the other can dial in a projectile), and the rifle doesn't have to be taken apart whatsoever to do any of it. Figure out what reg pressure with how many hammer spring clicks it likes with that setting and projectile and have at it.
