Greetings gentlemen. This looks like a great forum. I've been a Grendel fan for quite some time. I made the mistake of selling one years ago when I was made an offer I should have refused, but alas did not.
In any case, I'm back in the fold. I bought a 12.5" Noveske barrel and was so happy with the results, I picked up a 20" as well. Tomorrow I'll have some chrono numbers out of the 20.
The 12.5" has put up some numbers I'm very pleased with. Priv Part 120 BTHP and Hornady 123 SST both run a hair over 2300 FPS and Underwood 110 "Controlled Chaos" makes 2400.
More importantly, the accuracy is outstanding. My primary application is pigs in south Texas, so I'm using a 3.5x ACOG with the big red chevron/circle which is well calibrated to get you out to 300. I was pleased to see a 1.5" 5 shot group with the Underwood at 200 yards using the ACOG when initially trying out various types of ammo. The PP and Hornaday also shot well, reliably 1" ish at 100 with the Hornady, 1.25-1.5" with the PPU.
Then I managed to break the ACOG (!) and while it went out for repair I slapped a 3-18X on top out of sheer curiosity and was very pleased to see that off a rest at 100 yards, they rifle was shooting about .5" with the Underwood ammo.
I can only imagine what it's capable of with a real shooter off a legit bench.
Thus far, a couple hundred rounds and zero malfunctions.
The 20" is wearing an old USO SR6 1.5-6 which is to say it is very much set up for faster and closer but initial 40 rounds seem to indicate accuracy is excellent and kills pigs dead. Out to 300, it yielded a 3.5" group which I assure was a whole lot of user error. At some point I may put on a higher magnification to see what it can really do.
In short, the run of those barrels appears to have yielded fast and accurate results. I wish they'd made a 14.5" but the 12.5" is fast enough.
