RTI Barrels

[EPG]

I thought I’d share some info regarding Prophet Performance (NOT Compact) barrels, as I had some confusion regarding the different calibers, lengths (full vs. compact) and now “versions” (Prophet I vs. Prophet II.

The full length Prophet Performance V1 barrels are 600mm length for .22, .25 and .30. The full length .177 PP barrel is 510mm. All 4 calibers are Lothar Walther barrels. (I understand that at one time in the past, RTI once used CZ barrels)

The .22 and .25 Prophet Performance 600mm barrels have polygonal (vs. standard) rifling. The .22 and .25 also have a slower twist rate than a standard LW barrel. These .22 and .25 barrels are proprietary to RTI (developed for them) and optimized for “long range” pellet shooting. The slow twist rate that helps keep pellets stable at high velocities is not optimal for slug shooting.

Now the Prophet Performance II is coming out. From what I have read, RTI has changed the 600mm .22 and .25 barrels - so that they shoot slugs better (perhaps increasing the twist rate or reducing the choke - who knows?) So, if you have the v1 barrel in say .22, you may still want to buy a v2 .22 barrel (when they become available) for slug shooting.


I don’t know what types of barrels are used in any

the Prophet Compact series guns.

The barrel in my Prophet Performance .177 is a LW Standard 510 mm 



Pretty tight, when I first got it - A good polish of the entire barrel and the choke helped A LOT

That's my understanding as well.. my Prophet performance has the 600mm long range pellet barrel... someone will have to pry it outta my cold hands before I give it up. It shoots great!

give the 25 gr Jumbo Monsters. I turned my reg up to 125 shot a few of those just now and WOW.
I can only go to 85 yards with where I have my shooting table set up now, but pretty much one hole groups.

Been at work. Down in oil fields. Ready to get home and get back on my Prophet. Wife says birds going after fig crop. Hmmmm targets of opportunity. Have large supply of JSB 18.13. Do want to try the Monster redesigned when I can find them....the Prophet shoots better than I can....consistent hits at 100yds as long as I do my part proper.
