Vihta Vuori N133 in a 6.5 Grendel AR?

Since it seems VV N133 is so popular with the 6PPC benchrest crowd, I was wondering how an AR with the 6.5 Grendel would like VV N133. The Grendel is based on the same case as the PPC, the bullet diameters aren't dramatically different, and the burn rate is even close to H335. Anyone ever use it in a Grendel?
Thanks,
Ken

It may not have the correct burn rate for the ARs gas system. You may have to go to the 500 series. N140 wouldn't work in my 6x47 Lapua but N560 did.

Just remembered....You may want to try Accurate 2520 with the 123 gr. bullets. According to Alexander Arms, it gave high velocities. I've used in other cal. ARs and found it to be very, very accurate.

Not sure on that, think it is too fast. Powders that seem to work for 6.5 Grendel and 123gr projectiles.

AA 2520
TAC
These were the early to favorites.

XBR 8208
CFE 223
Leverevolution
These have been more in favor lately. But don't count out the first two.

I have have used all but CFE.

I use N133, but in a 223 Remington AR-15, which happens to be the accuracy load from Sierra for 52/52 grain bullets. I tried it and it seemed to work great, plus it has a reputation for being clean burning. I know this is not all so applicable to the 6.5 Grendel, but it does seem to work in a semi-auto. I will say I have a few failure to pick up a new round from the mag with it, but think that was due to another problem.

Phil3, IMHO, I think you should re-examine the 133 powder. Not having the proper burn rate does lead, among other problems, to short stroking and not picking up the next round. I'm no expert, but I do think that unless you found another culprit for your short strokes/failure to feed, the powder could very well be it.
