My personal experience/opinion so take it with a grain of salt.
The steel barreled B14Rs shoot well with most ammo but great but great with lot tested ammo.
Kenny at DPG builds excellent CZs, Bergaras, RimX, Voodoos but guarantees 0.3" for 5 shot groups at 50.
Some may scoff at 0.3" but for practical shooting, this is plenty.
Granted, his rifle builds seem to be less finicky with ammo but his builds are usually are longer barrels which I've read can reduce SD and "settle" the bullet better than shorter options. To me, "settle" seems to mean decreased procession or bullet wobble resulting in less BC degradation with longer distances.
For NRL22, 100 yards is the normal max range unless they choose the farther distance stage options or if the match director wants to do a bonus stage. 0.47" 5 shot groups at 50 yards is adequate to do the job since the smallest target I've encountered were 0.25" KYL @ 50 yards.
1.5" 5 shot groups at 100 yards seem to be more than adequate for NRL22.
IMHO where you will start seeing differences are shots past 200 yards (ie: NRL22x or PRS22 matches) and when shooting off barricades that needs the rifle to be balanced (ie: tripods are impractical or not allowed). In these situations, a longer, heavier, higher end barrels tend to do better.
Some Bergaras have weak ejection issues but with ~4000 rounds fired, I've not experienced it. Don't stake the ejectors before ever sending a round down range! I've seen people introduce a problem even before seeing if it worked.
Lastly, IF I had to start all over again, I would buy a used Carbon Barreled B14R on a discount, then send the barrel to Modacam and have them fit a 22-24" truck axle barrel and put it in a stock/chassis of your choice.
YMMV, happy shooting.
