Home Forums Hunting & Shooting Custom Rifles & Wildcats PacNor Polygonal rifling?

Does anyone have experience with PacNor polygonal rifled barrels in .224 caliber? Lothar Walther seems to be the gold standard in polygonal, just wondering how PacNor compares?

JME, If you are going to buy a Pac Nor 22Cal just go with the 5groove and you will be happy. I'm not a fan of the 3groove or the polygonal

Could you tell me or us why your not a fan of 3 groove or the polygonal?

Tell us why you want it? What does it offer?

If Lothar is the gold standard, why are you slumming with a Pacnor?

I thought Gary Schneider was the gold standard

I've had good luck with PacNor 3-grooves with 3 of them on AR Service Rifles. One 8 twist and two 6.5 twists. Holliger paid to have the 6.5 button ground and the AMU took advantage of that and used few at long range to good effect.

With that experience, I bought a 7 twist polygonal from PacNor. But it's sat unchambered on the sidelines for a while now (well before the fire). In fact I was just reminded that I needed to decide what to do with it (after I figure out how I'm going to use the Obermeyer parked there as well). They don't seem to have caught on in the highpower world. I'll ask John about his experiences with them.

I'll take a 3 groove small cal everytime over any other groove, ive got i believe 8 17-20 cals that are 3 groove.
That being said a good barrel is a good barrel

Schneider retired.

I did say " was"

I have one on a 6.5 WSM. I can't say it is more or any less accurate the Ballard or 5R rifling. They are easier to clean. They might be faster, but with a sample of 1, I wouldn't know how to tell. It just gives me a warm fuzzy - that's why I have 1

They aren't more accurate, they just last longer and clean easier. They don't like some bullets

FWIW, I’ve got a Black Hole Polygonal AR 1:8 barrel. It cleans easily, but hates heavies (73 eldms, 75 BTHP’s). It shoots 55 SPT’s into little clusters and does things with 53 V-Max’s that defy belief.

As far as speed claims, I’ve never done any testing in that regard.

That said; I’ve got a 5R .22BR that’s simply amazing with anything and that’ll be the route I go for any bolt gun from now on. It’s a Bartlein, but I can’t imagine Pac-Nor would be much different.

I have a 7 STW, 3 groove, 11 twist, short freebore that Pac Nor barreled. 140's at 3650 shooting bug holes are the norm, took 12 rounds to work up a load.

Heard back from Holliger. My polygonal Pac-Nor is a 6.5 twist. I remember now...I had hoped the polygonal rifling would be gentler on the 90's I was playing with and less likely to cause a poof as hard as we were pushing them. I guess I moved on from the 90's before I could get that one spun up. Time to figure out what to do with it.

Oh yeah...Holliger only sold a few Pac-Nor Polys and doesn't recall much in the way of feedback.

I’m having a 28 Nosler built with a PacNor 8 twist with polygonal rifling. Should be done in a month or so, I’ll post results once it’s completed.
