Following up my previous thread regarding 75 yard results with the JTS .22 22.07g using the FX Dreamline PowerPup...
After the positive results with the JTS 22.07g at 75 yards in the FX rifle, I pulled my RTI Prophet Performance V1 out of the truck to test the JTS 29.63g domes.
The Prophet has RTI's .25 LR (Long Range) barrels in it. I actually have two of these .25LR barrels as well as the more common .22LR barrel (also a .177 and a .30). Many folks don't know the .25LR (1:32 twist rate - same TR as .22LR barrel) barrels exist - as up until the last year of Prophet V1 production, RTI used CZ barrels in .25 caliber.
I've found both of my .25LR barrels to be phenomenal performers. I've gotten some results that make me shake my head with these barrels - better results than my level of shooting deserves, lol. Interestingly, the .25LR is the only RTI barrel that is not threaded on the muzzle end for the shroud spacer. The .25LR actually has an air stripper that is pressed/glued on. Even more interesting is that the air stripper is different between my two .25LRs.
In any case, this .25LR is virtually new - only has probably 100-125 pellets through it. All pellets were FX 25.4g. It was zeroed at 40 yards to shoot the 25.4g @ 880fps.
So, I'm doing an initial pellet test at 75 yards - without a single JTS 29.63g having even been down this barrel. The 29.63g had shot great out of my 600mm FX Crown Mk2.
I had not shot this Prophet since last fall (I have two Prophet V1s - fantastic rifle - I'd recommend a V1 Prophet to any pellet shooter).
I did a couple dry fires to reset the plenum and chronoed an initial shot - low 800s as the JTS were heavier than the 25.4s. I had guessed (from experience) about 50 clicks up (from 40 yard zero) on the Sightron SIII to get near the PoA at 75 yards.
The cool thing about the Prophet V1 is that you can adjust the trigger sear engagement, trigger spring weight, hammer spring preload and regulator pressure (up and down) - all while leaving the rifle in your shooting rest on the bench. Haven't seen another rifle that is so easily adjustable. I actually bumped up the reg pressure to 120bar - and then gradually increased the velocity group-by-group with the hammer spring.
Here are the results. Remember from my previous post that it was windy - too windy to continue my .30 cal 100 yard practice. So, a few shots blew wide.
As before, the groups were shot at a single point of aim - the white dots. The paper plate were shot with me trying to hit the 1/2" center dots - so I kept changing my hold offs on the plates. The plates were shot with the velocity dialed up to 891-895fps. Despite me changing both reg pressure and hammer spring, check out how nice the velocity spread was that I was getting.
Dang, I'm really impressed with these JTS 29.63g. I almost kept all 30+ shots at the plates on or touching a 2" splatter at 75 yards in the wind. The third plate was really nice.

. My daystate barrel really likes that jts pellet too. My eyes are wide open to jts pellets. They are quickly replacing jsb in my orders.
