I'm looking at the new Jsa Raptor with poly barrels in .22 and .25. The pellet barrels are choked, the slug barrel not. Are the poly barrels better? Will an unchoked barrel be accurate with pellets? It sounds like some of the Fx smooth twist X slug liners do well with pellets. What's the verdict on "poly" barrels?
Polygon barrels?

Polygonal barrels do best with pellets at 900 FPS or faster. 950-on up for whatever your twist is & projectile length/caliber will stabilize.
I have barrels with no chokes that can shoot pellets & slugs equally well if 1/4” c-t-c at 40 yards is well. It does better with slugs way further out.
I prefer to shoot everything at 880-900 but I am considering a 28-32” .177 Polygonal for pellets only, & that means heaviest .177’s I can get at 950 or more. Testing would tell but if I go with no choke .177 for 15-29 grain slugs than traditional rifling will be used and 28-32” faster than 1:16”. Depending on platform I barrel & loading gate length I’m limited by. Alterations can easily be done.

My new brocock bantam sniper HP mag 22 cal has a polygonal barrel and to this point I haven’t found a slug that works
i was playing around shooting at 100 yards today. I have two guns a cricket 25 and the Brocock in 22. The cricket will send 34 gr JSB to 100 and hit my smallest swinger most every time. I’d say the singer is 2.5 inches. It definitely is shooting better at 100 then brocock so far.
To this point with my limited experience like in all shooting it’s barrels a bullets. My suspicion is to shoot slugs you need a slug specific barrel and it’s probably not polygonal

Poly barrels are generally less accurate than the barrels with traditional rifling. They also catch lead much faster.

As evidenced by the Daystate Red Wolf with a Poly Barrel and the Brocock that 2018 EBR was WON with and of course the notoriously inaccurate Thomas Bench Rifles.
I don't think your statement is correct! Reverse your statement and you will be MUCH closer to correct!Upvote 0

How about RMAC this year? How many traditionally rifled guns won?

Just a wild guess ..... ZERO! O yea I forgot about those "horribly inaccurate" RAW's in my original post above

Both AZ and Martin at Raw have told me that the polygon barrels lead up faster than other barrels. I decided not to go with one because of that information. But if you can get super incredible accuracy with pellets in a polygon barrel, then it would probably be worth it even if you have to clean it more often. I don’t think I’m a good enough shot to notice the difference anyway! But the guys who are shooting the impacts and slugs so accurately and at such long distance would probably notice the difference in accuracy. I gotta admit that I would love a Redwolf in .177 though.

Regarding the leading, was that for pellets or slugs or both, and also choked or not?
from what Steve at AEAC said he experienced on the sniper magnum in the recent review
the poly barrel had far LESS leading than a traditionally rifled barrel, at least in his real world test of the LW poly in the brocock magnum.
on the GTA forums neilsenammo had noted that it would be very important on a poly barrel to match the diameters to the barrel in a poly, so perhaps that means they are more sensitive to getting the "right" slug, than say a liner designed for slugs specifically?

To say that POLY barrels "foul" faster may be a factor of the application, generally POLY barrels are used for higher speeds and energy levels.
Push any object harder and faster down a barrel and it will foul faster.
POLY barrels generally impart less damage to the surface of the projectile, hence they can be used at higher velocities etc. so fouling would be a natural side effect of this.
However to say that a fouled barrel will always shoot worse than a clean one is nonsense I'm afraid.
