I have loaded competition bullets for several cartridges, and they all shot very, very well. I don't think you'll be disappointed in the competition bullet for accuracy.
I've used them extensively in .30 cal. Literally thousands and thousands of them through several barrels. Typically the Noslers shoot very well, right up there with the Sierra Matchking.
Sometimes the Berger VLD's shoot better for me, but often they're a little picky about seating depth. The Nosler and Sierra match bullets don't seem to really care that much about seating depth... A little jump to the lands is just fine with them.
Both of my 223s shoot the Nosler 52gr very well, and my Swede does a good job of putting the 140 gr Nosler CC in small groups. It`s a great bullet IMO.
