RPB barrel in my RTI Prophet Performance 1st generation

[jmohme]

I ordered a RPB barrel in 25 caliber for the RTI Arms shop back in November. It was delivered just before I was heading out for several weeks away so I did not get to install it until yesterday.
I had some time so I did a quick bore cleaning and polish I installed it and the .25 pellet probe. loaded some JSB King Heavy 33.95 gr pellets and headed out to my backyard range.

I set up a target on my 50 yard backstop. The first shot was low. The second also low but right on top of the first. I made adjustments to my scope and the next 8 shots were all right on target. This without changaing anything from my tune for the .22 LR barrel that it replaced.

Next up were a few FX Hybrid slugs. POI was higher than the pellets, but again hole on hole.

Back to the JSBs. I shot 60 shots with amazing accuracy and consistency. I really was not expecting this one to outperform the 22 Lr, but it did. Very pleased with this new barrel.

Next I need to get out the Chronograph and do some actual testing and fine tuning, but it is raining here today, so that will have to wait.
I almost dont want to mess with the tune. It just seems near perfect where it is.

Hi

Would you mind sharing some information on your experience with the .25 hybrids in that barrel? I ordered some of the lighter slug offerings ( hybrids, hn 28 grain, nsa 29 grain) in the hopes of shooting both slugs and king heavies as you describe. Any chance you mind sharing speeds / reg pressure if you have them? I realise each barrel is different but it would give me something to start with..  currently have the king heavies flying at 892 and they are great! The p3 is definitly more accurate then I am…

Thank you!
